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

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

1. Unstained cells.

2. Cells stained with FITC Annexin V (no PI).

3. Cells stained with PI (no FITC 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 FITC Annexin V and/or FITC

Annexin V and PI. 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 (FITC Annexin V

positive, PI negative or FITC Annexin V positive, PI 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 PI as well as for FITC 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 FITC

Annexin V and PI.

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.

BD细胞凋亡试剂盒(PE和7-ADD标记)PE Annexin V Apoptosis Detection Kit I

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.
