简单介绍:

 在正常细胞中,***脂酰丝氨酸只分布在细胞膜脂质双层的内侧,细胞发生凋亡zui早期,膜***脂酰丝氨酸(PS)由脂膜内侧翻向外侧,这一变化早于细胞皱缩、染色质浓缩、DN**断化和细胞膜的通透性增加等凋亡现象。AnnexinV是一种***脂结合蛋白,与***脂酰丝氨酸有高度亲和力,故可通过细胞外侧暴露的***脂酰丝氨酸与凋亡早期细胞的胞膜结合。因此AnnexinV被作为检测细胞早期凋亡的灵敏指标之一。***化丙***(Propidium Iodide,PI)是一种核酸染料,它不能透过完整的细胞膜,但凋亡中晚期的细胞和死细胞由于细胞膜通透性的增加,PI能够透过细胞膜而使细胞核染红。因此将Annexin V与PI匹配使用,就可以将处于不同凋亡时期的细胞区分开来。

Description

Apoptosis is a normal physiologic process which occurs during embryonic development as well as in maintenence of tissue homeostasis. The

apoptotic program is characterized by certain morphologic features, including loss of plasma membrane asymmetry and attachment,

condensation of the cytoplasm and nucleus, and internucleosomal cleavage of DNA. Loss of plasma membrane is one of the earliest features.

In apoptotic cells, the membrane phospholipid phosphatidylserine (PS) is translocated from the inner to the outer leaflet of the plasma

membrane, thereby exposing PS to the external cellular environment. Annexin V is a 35-36 kDa Ca2+ dependent phospholipid-binding

protein that has a high affinity for PS, and binds to cells with exposed PS. Annexin V may be conjugated to fluorochromes including

Phycoerythrin (PE). This format retains its high affinity for PS and thus serves as a sensitive probe for flow cytometric analysis of cells that are

undergoing apoptosis. Since externalization of PS occurs in the earlier stages of apoptosis, PE Annexin V staining can identify apoptosis at an

earlier stage than assays based on nuclear changes such as DNA fragmentation.

PE Annexin V staining precedes the loss of membrane integrity which accompanies the latest stages of cell death resulting from either

apoptotic or necrotic processes. Therefore, staining with PE Annexin V is typically used in conjunction with a vital dye such as

7-Amino-Actinomycin (7-AAD) to allow the investigator to identify early apoptotic cells (7-AAD negative, PE Annexin V positive). Viable

cells with intact membranes exclude 7-AAD, wheras the membranes of dead and damaged cells are permeable to 7-AAD. For example, cells

that are considered viable are PE Annexin V and 7-AAD negative; cells that are in early apoptosis are PE Annexin V positive and 7-AAD

negative; and cells that are in late apoptosis or already dead are are both PE Annexin V and 7-AAD positive. This assay does not distinguish

between cells that have undergone apoptotic death versus those that have died as a result of a necrotic pathway because in either case, the dead

cells will stain with both PE Annexin V and 7-AAD. However, when apoptosis is measured over time, cells can be often tracked from PE

Annexin V and 7-AAD negative (viable, or no measurable apoptosis), to PE Annexin V positive and 7-AAD negative (early apoptosis,

membrane integrity is present) and finally to PE Annexin V and 7-AAD positive (end stage apoptosis and death). The movement of cells

through these three stages suggests apoptosis. In contrast, a single observation indicating that cells are both PE Annexin V and 7-AAD

positive, in of itself, reveals less information about the process by which the cells underwent their demise.

Flow Cytometric Analysis of PE Annexin V staining. Jurkat cells

(Human T-cell leukemia; ATCC TIB-152) were left untreated (top

panels) or treated for 4 hours with 4 μM Camptothecin (bottom

panels). Cells were incubated with PE Annexin V in a buffer

containing 7-Amino-Actinomycin (7-AAD) and analyzed by flow

cytometry. Untreated cells were primarily PE Annexin V and 7-AAD

negative, indicating that they were viable and not undergoing

apoptosis. After a 4 hour treatment (bottom panels), there were

primarily two populations of cells: Cells that were viable and not

undergoing apoptosis (PE Annexin V and 7-AAD negative); cells

undergoing apoptosis (PE Annexin V positive and 7-AAD negative).

A minor population of cells were observed to be PE Annexin V and

7-AAD positive, indicating that they were in end stage apoptosis or

already dead.

Preparation and Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Application Notes

Application

Flow cytometry Routinely Tested

Recommended Assay Procedure:

PE Annexin V is a sensitive probe for identifying apoptotic cells, binding to negatively charged phospholipid surfaces (Kd of ~5 x 10^-2) with a

higher affinity for phosphatidylserine (PS) than most other phospholipids. PE Annexin V binding is calcium dependent and defined calcium and

salt concentrations are required for optimal staining as described in the PE Annexin V Staining Protocol. Investigators should note that PE

Annexin V flow cytometric analysis on adherent cell types (e.g HeLa, NIH 3T3, etc.) is not routinely tested as specific membrane damage

may occur during cell detachment or harvesting. Methods for utilizing Annexin V for flow cytometry on adherent cell types, however,

have been previously reported (Casiola-Rosen et al. and van Engelend et al.).

INDUCTION OF APOPTOSIS BY CAMPTOTHECIN

The following protocol is provided as an illustration on how PE Annexin V may be used on a cell line (Jurkat).

BD*凋亡检测试剂盒(PE,7-ADD,FITC标记)559763 556547

Materials

1. Prepare Camptothecin stock solution (Sigma-Aldrich Cat. No. C-9911): 1 mM in DMSO.

2. Jurkat T cells (ATCC TIB-152).

Procedure

1. Add Camptothecin (final conc. 4-6 μM) to 1 x 10^6 Jurkat cells.

2. Incubate the cells for 4-6 hr at 37°C.

3. Proceed with the PE Annexin V Staining Protocol to measure apoptosis.

PE ANNEXIN V STAINING PROTOCOL

PE Annexin V is used to quantitatively determine the percentage of cells within a population that are actively undergoing apoptosis. It relies on

the property of cells to lose membrane asymmetry in the early phases of apoptosis. In apoptotic cells, the membrane phospholipid

phosphatidylserine (PS) is translocated from the inner leaflet of the plasma membrane to the outer leaflet, thereby exposing PS to the external

environment. Annexin V is a calcium-dependent phospholipid-binding protein that has a high affinity for PS, and is useful for identifying

apoptotic cells with exposed PS. 7-Amino-Actinomycin (7-AAD) is a standard flow cytometric viability probe and is used to distinguish viable

from nonviable cells. Viable cells with intact membranes exclude 7-AAD, whereas the membranes of dead and damaged cells are permeable to

7-AAD. Cells that stain positive for PE Annexin V and negative for 7-AAD are undergoing apoptosis. Cells that stain positive for both PE

Annexin V and 7-AAD are either in the end stage of apoptosis, are undergoing necrosis, or are already dead. Cells that stain negative for both PE

Annexin V and 7-AAD are alive and not undergoing measurable apoptosis.

559763 Rev. 8 Page 2 of 3

Reagents

1. PE Annexin V (component no. 51-65875X): Use 5 μl per test.

2. 7-Amino-Actinomycin (7-AAD) (component no. 51-68981E) is a convenient, ready-to-use nucleic acid dye. Use 5 μl per test.

3. 10X Annexin V Binding Buffer (component no. 51-66121E): 0.1 M Hepes/NaOH (pH 7.4), 1.4 M NaCl, 25 mM CaCl2. For a 1X working

solution, dilute 1 part of the 10X Annexin V Binding Buffer to 9 parts of distilled water.

Staining

1. Wash cells twice with cold PBS and then resuspend cells in 1X Binding Buffer at a concentration of 1 x 10^6 cells/ml.

2. Transfer 100 μl of the solution (1 x 10^5 cells) to a 5 ml culture tube.

3. Add 5 μl of PE Annexin V and 5 μl 7-AAD.

4. Gently vortex the cells and incubate for 15 min at RT (25°C) in the dark.

5. Add 400 μl of 1X Binding Buffer to each tube. Analyze by flow cytometry within 1 hr.

SUGGESTED CONTROLS FOR SETTING UP FLOW CYTOMETRY

The following controls are used to set up compensation and quadrants:

1. Unstained cells.

2. Cells stained with PE Annexin V (no 7-AAD).

3. Cells stained with 7-AAD (no PE Annexin V).

Other Staining Controls:

A cell line that can be easily induced to undergo apoptosis should be used to obtain positive control staining with PE Annexin V and/or PE

Annexin V and 7-AAD. It is important to note that the basal level of apoptosis and necrosis varies considerably within a population. Thus, even in

the absence of induced apoptosis, most cell populations will contain a minor percentage of cells that are positive for apoptosis (PE Annexin V

positive, 7-AAD negative or PE Annexin V positive, 7-AAD positive).

The untreated population is used to define the basal level of apoptotic and dead cells. The percentage of cells that have been induced to undergo

apoptosis is then determined by subtracting the percentage of apoptotic cells in the untreated population from percentage of apoptotic cells in the

treated population. Since cell death is the eventual outcome of cells undergoing apoptosis, cells in the late stages of apoptosis will have a damaged

membrane and stain positive for 7-AAD as well as for PE Annexin V. Thus the assay does not distinguish between cells that have already

undergone an apoptotic cell death and those that have died as a result of necrotic pathway, because in either case the dead cells will stain with

both PE Annexin V and 7-AAD.

Product Notices

This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-μl experimental

sample (a test).

Apoptosis is a normal physiologic process which occurs during embryonic development as well as in maintenence of tissue homeostasis. The

apoptotic program is characterized by certain morphologic features, including loss of plasma membrane asymmetry and attachment,

condensation of the cytoplasm and nucleus, and internucleosomal cleavage of DNA. Loss of plasma membrane is one of the earliest features.

In apoptotic cells, the membrane phospholipid phosphatidylserine (PS) is translocated from the inner to the outer leaflet of the plasma

membrane, thereby exposing PS to the external cellular environment. Annexin V is a 35-36 kDa Ca2+ dependent phospholipid-binding

protein that has a high affinity for PS, and binds to cells with exposed PS. Annexin V may be conjugated to fluorochromes including

Phycoerythrin (PE). This format retains its high affinity for PS and thus serves as a sensitive probe for flow cytometric analysis of cells that are

undergoing apoptosis. Since externalization of PS occurs in the earlier stages of apoptosis, PE Annexin V staining can identify apoptosis at an

earlier stage than assays based on nuclear changes such as DNA fragmentation.

PE Annexin V staining precedes the loss of membrane integrity which accompanies the latest stages of cell death resulting from either

apoptotic or necrotic processes. Therefore, staining with PE Annexin V is typically used in conjunction with a vital dye such as

7-Amino-Actinomycin (7-AAD) to allow the investigator to identify early apoptotic cells (7-AAD negative, PE Annexin V positive). Viable

cells with intact membranes exclude 7-AAD, wheras the membranes of dead and damaged cells are permeable to 7-AAD. For example, cells

that are considered viable are PE Annexin V and 7-AAD negative; cells that are in early apoptosis are PE Annexin V positive and 7-AAD

negative; and cells that are in late apoptosis or already dead are are both PE Annexin V and 7-AAD positive. This assay does not distinguish

between cells that have undergone apoptotic death versus those that have died as a result of a necrotic pathway because in either case, the dead

cells will stain with both PE Annexin V and 7-AAD. However, when apoptosis is measured over time, cells can be often tracked from PE

Annexin V and 7-AAD negative (viable, or no measurable apoptosis), to PE Annexin V positive and 7-AAD negative (early apoptosis,

membrane integrity is present) and finally to PE Annexin V and 7-AAD positive (end stage apoptosis and death). The movement of cells

through these three stages suggests apoptosis. In contrast, a single observation indicating that cells are both PE Annexin V and 7-AAD

positive, in of itself, reveals less information about the process by which the cells underwent their demise.

Flow Cytometric Analysis of PE Annexin V staining. Jurkat cells

(Human T-cell leukemia; ATCC TIB-152) were left untreated (top

panels) or treated for 4 hours with 4 μM Camptothecin (bottom

panels). Cells were incubated with PE Annexin V in a buffer

containing 7-Amino-Actinomycin (7-AAD) and analyzed by flow

cytometry. Untreated cells were primarily PE Annexin V and 7-AAD

negative, indicating that they were viable and not undergoing

apoptosis. After a 4 hour treatment (bottom panels), there were

primarily two populations of cells: Cells that were viable and not

undergoing apoptosis (PE Annexin V and 7-AAD negative); cells

undergoing apoptosis (PE Annexin V positive and 7-AAD negative).

A minor population of cells were observed to be PE Annexin V and

7-AAD positive, indicating that they were in end stage apoptosis or

already dead.

Preparation and Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Application Notes

Application

Flow cytometry Routinely Tested

Recommended Assay Procedure:

PE Annexin V is a sensitive probe for identifying apoptotic cells, binding to negatively charged phospholipid surfaces (Kd of ~5 x 10^-2) with a

higher affinity for phosphatidylserine (PS) than most other phospholipids. PE Annexin V binding is calcium dependent and defined calcium and

salt concentrations are required for optimal staining as described in the PE Annexin V Staining Protocol. Investigators should note that PE

Annexin V flow cytometric analysis on adherent cell types (e.g HeLa, NIH 3T3, etc.) is not routinely tested as specific membrane damage

may occur during cell detachment or harvesting. Methods for utilizing Annexin V for flow cytometry on adherent cell types, however,

have been previously reported (Casiola-Rosen et al. and van Engelend et al.).

INDUCTION OF APOPTOSIS BY CAMPTOTHECIN

The following protocol is provided as an illustration on how PE Annexin V may be used on a cell line (Jurkat).

Materials

1. Prepare Camptothecin stock solution (Sigma-Aldrich Cat. No. C-9911): 1 mM in DMSO.

2. Jurkat T cells (ATCC TIB-152).

Procedure

1. Add Camptothecin (final conc. 4-6 μM) to 1 x 10^6 Jurkat cells.

2. Incubate the cells for 4-6 hr at 37°C.

3. Proceed with the PE Annexin V Staining Protocol to measure apoptosis.

PE ANNEXIN V STAINING PROTOCOL

PE Annexin V is used to quantitatively determine the percentage of cells within a population that are actively undergoing apoptosis. It relies on

the property of cells to lose membrane asymmetry in the early phases of apoptosis. In apoptotic cells, the membrane phospholipid

phosphatidylserine (PS) is translocated from the inner leaflet of the plasma membrane to the outer leaflet, thereby exposing PS to the external

environment. Annexin V is a calcium-dependent phospholipid-binding protein that has a high affinity for PS, and is useful for identifying

apoptotic cells with exposed PS. 7-Amino-Actinomycin (7-AAD) is a standard flow cytometric viability probe and is used to distinguish viable

from nonviable cells. Viable cells with intact membranes exclude 7-AAD, whereas the membranes of dead and damaged cells are permeable to

7-AAD. Cells that stain positive for PE Annexin V and negative for 7-AAD are undergoing apoptosis. Cells that stain positive for both PE

Annexin V and 7-AAD are either in the end stage of apoptosis, are undergoing necrosis, or are already dead. Cells that stain negative for both PE

Annexin V and 7-AAD are alive and not undergoing measurable apoptosis.

Reagents

1. PE Annexin V (component no. 51-65875X): Use 5 μl per test.

2. 7-Amino-Actinomycin (7-AAD) (component no. 51-68981E) is a convenient, ready-to-use nucleic acid dye. Use 5 μl per test.

3. 10X Annexin V Binding Buffer (component no. 51-66121E): 0.1 M Hepes/NaOH (pH 7.4), 1.4 M NaCl, 25 mM CaCl2. For a 1X working

solution, dilute 1 part of the 10X Annexin V Binding Buffer to 9 parts of distilled water.

Staining

1. Wash cells twice with cold PBS and then resuspend cells in 1X Binding Buffer at a concentration of 1 x 10^6 cells/ml.

2. Transfer 100 μl of the solution (1 x 10^5 cells) to a 5 ml culture tube.

3. Add 5 μl of PE Annexin V and 5 μl 7-AAD.

4. Gently vortex the cells and incubate for 15 min at RT (25°C) in the dark.

5. Add 400 μl of 1X Binding Buffer to each tube. Analyze by flow cytometry within 1 hr.

SUGGESTED CONTROLS FOR SETTING UP FLOW CYTOMETRY

The following controls are used to set up compensation and quadrants:

1. Unstained cells.

2. Cells stained with PE Annexin V (no 7-AAD).

3. Cells stained with 7-AAD (no PE Annexin V).

Other Staining Controls:

A cell line that can be easily induced to undergo apoptosis should be used to obtain positive control staining with PE Annexin V and/or PE

Annexin V and 7-AAD. It is important to note that the basal level of apoptosis and necrosis varies considerably within a population. Thus, even in

the absence of induced apoptosis, most cell populations will contain a minor percentage of cells that are positive for apoptosis (PE Annexin V

positive, 7-AAD negative or PE Annexin V positive, 7-AAD positive).

The untreated population is used to define the basal level of apoptotic and dead cells. The percentage of cells that have been induced to undergo

apoptosis is then determined by subtracting the percentage of apoptotic cells in the untreated population from percentage of apoptotic cells in the

treated population. Since cell death is the eventual outcome of cells undergoing apoptosis, cells in the late stages of apoptosis will have a damaged

membrane and stain positive for 7-AAD as well as for PE Annexin V. Thus the assay does not distinguish between cells that have already

undergone an apoptotic cell death and those that have died as a result of necrotic pathway, because in either case the dead cells will stain with

both PE Annexin V and 7-AAD.

详细介绍

FITC标记细胞凋亡检测试剂盒Annexin V-FITC(Annexin V-FITC Apoptosis Detection Kit)是用FITC标记的重组人Annexin V来检测细胞凋亡时出现在细胞膜表面的磷酯酰丝氨酸的一种细胞凋亡检测试剂盒。可以使用流式细胞仪、荧光显微镜或其它荧光检测设备进行检测。
Annexin是一类广泛分布于真核细胞细胞浆内钙离子依赖的磷酯结合蛋白,参与细胞内的信号转导。但仅Annexin V被报道可以调控一些PKC的活性。
FITC标记细胞凋亡检测试剂盒Annexin V-FITC

Annexin V选择性结合磷酯酰丝氨酸(phosphatidylserine,简称PS)。磷酯酰丝氨酸主要分布在细胞膜内侧,即与细胞浆相邻的一侧。在细胞发生凋亡的早期,不同类型的细胞都会把磷酯酰丝氨酸外翻到细胞表面,即细胞膜外侧。磷酯酰丝氨酸暴露到细胞表面后会促进凝血和炎症反应。而Annexin V和外翻到细胞表面的磷酯酰丝氨酸结合后可以阻断磷酯酰丝氨酸的促凝血和促炎症反应活性。
用带有绿色荧光的荧光探针FITC标记的Annexin V,即Annexin V-FITC,就可以用流式细胞仪或荧光显微镜非常简单而直接地检测到磷酯酰丝氨酸的外翻这一细胞凋亡的重要特征。
本试剂盒还提供了碘化丙啶染色液,碘化丙啶可以染色坏死细胞或凋亡晚期丧失细胞膜完整性的细胞,呈现红色荧光。对于坏死细胞,由于细胞膜的完整性已经丧失,Annexin V-FITC可以进入到细胞浆内,与位于细胞膜内侧的磷酯酰丝氨酸结合,从而也使坏死细胞呈现绿色荧光。
综上所述,参考下图,用Annexin V-FITC和碘化丙啶染色后,正常的活细胞不被Annexin V-FITC和碘化丙啶染色(下图左下角);凋亡早期的细胞仅被Annexin V-FITC染色,碘化丙啶染色呈阴性(下图右下角);坏死细胞和凋亡晚期的细胞可以同时被Annexin V-FITC和碘化丙啶染色(下图右上角)。下图左上角出现的是许可范围内的检测误差。

  • 产品型号:  C1052

详细介绍

细胞周期与细胞凋亡检测试剂盒Cell Cycle and Apoptosis Analysis KiT

碘化丙啶(Propidium,简称PI)是一种双链DNA的荧光染料。碘化丙啶和双链DNA结合后可以产生荧光,并且荧光强度和双链DNA的含量成正比。细胞内的DNA被碘化丙啶染色后,可以用流式细胞仪对细胞进行DNA含量测定,然后根据DNA含量的分布情况,可以进行细胞周期和细胞凋亡分析。
碘化丙啶染色后,假设G0/G1期细胞的荧光强度为1,那么含有双份基因组DNA的G2/M期细胞的荧光强度的理论值为2,正在进行DNA复制的S期细胞的荧光强度为1-2之间。凋亡细胞由于细胞核发生浓缩以及发生DNA片段化(DNA fragmentation)导致部分基因组DNA片断在染色过程中丢失,因此凋亡细胞碘化丙啶染色后呈现明显的弱染,即荧光强度小于1,在流式检测的荧光图上出现所谓的sub-G1峰,即凋亡细胞峰。
细胞发生凋亡时,由于胞浆和染色质浓缩、核碎裂,产生凋亡小体,使细胞的光散射性质发生变化。在细胞凋亡的早期,细胞对前向角光散射的能力显著降低,对侧向光散射的能力增加或没有变化。在细胞凋亡的晚期,前向和侧向光散射的信号均降低。因此可通过流式细胞仪测定细胞光散射的变化观察细胞凋亡情况。
本试剂盒通常应用于培养的贴壁或悬浮细胞的细胞周期与细胞凋亡检测。如果用于组织的细胞周期与细胞凋亡检测,则必须把组织消化成单细胞状态,才可以进行检测。
本试剂盒足够检测50个样品,每个样品的细胞数量可以为10-100万。
