Whatman 沃特曼 FAST Quant 40蛋白芯片

Whatman 沃特曼 FAST Quant 40蛋白芯片

简要描述:

Whatman 沃特曼 FAST Quant 40蛋白芯片,基于FAST技术,利用蛋白质与化学表面的高度结合,FAST Quant将芯片技术的定量能力与传统ELISA的高通量有机结合,比传统ELISA具有更好的灵敏度和重现性。

FAST Quant系统代表了目前蛋白质芯片研究的zui前沿。通过FAST Quant,研究者可以同时对多个生物样品中的细胞因子浓度进行精确的定量。

基于FAST技术,利用蛋白质与化学表面的高度结合,FAST Quant将芯片技术的定量能力与传统ELISA的高通量有机结合,比传统ELISA具有更好的灵敏度和重现性。

FAST Quant Kit包括810种抗人或鼠细胞因子的单抗(64个反应)。实验室耗材在芯片上从定量的方式平行点三次。

使用416-pad FAST Slides置于FAST Frame(单独定购)中,FAST Quant可提供与传统微孔板相同的8×12cm样式。标准曲线采用系列稀释的各种抗原作为标准。由于microspot芯片的固相表面性质,不需要每个样品均做复孔。MicroSpot ELISA反应完全只与浓度相关,而传统ELISA反应却依赖于浓度和体积两方面。

Sensitivity: 25.28 ± 1.68 pg/mL

Description:

Macrophage migration inhibitory factor (MIF), also known as glycosylation inhibiting factor (GIF), is a pituitary hormone and a macrophage- and T cell-derived cytokine that plays an important role in the endocrine and immune systems. MIF consists of 115 amino acids and has a molecular weight of 12.5 kD. Mouse MIF shares most of its identity with human (90%), rat (99%), and cattle (88%) MIFs, and a moderate percentage of its identity with MIFs from a wide variety of other species. It exists in monomeric, dimeric, and trimeric forms of identical protomers.

MIF is active as a pro-inflammatory regulator and upregulates multiple cytokines that are vital to combating infections in vivo, including tumor-necrosis factor (TNF), interferon-γ (IFN-γ), and interleukin-12 (IL-12). It is known to maintain cell survival and promote pro-inflammatory immune responses. MIF also activates the ERK1/ERK2 signaling pathway, which inhibits the immunosuppressive effects of glucocorticoids. MIF also plays a critical role in superantigen-induced toxic shock. It upregulates several factors that enhance the growth and invasiveness of gram-negative bacteria. MIF can enhance many inflammatory diseases, such as acute respiratory distress syndrome, arthritis, atopic dermatitis, allograft rejection, glomerulonephritis, inflammatory bowel diseases, asthma, and atherosclerosis. Known receptors for MIF include CXCR2, CXCR4, CD44, and CD74.

The LEGEND MAX™ Mouse MIF ELISA kit is a ready-to-use Sandwich Enzyme-Linked Immunosorbent Assay (ELISA) with a 96-well strip plate that is pre-coated with a rat monoclonal anti-mouse MIF antibody. The Detection Antibody is a biotinylated goat polyclonal anti-mouse MIF antibody. This assay is specifically designed to quantify mouse MIF from serum, plasma, cell culture supernatant, and cell lysate. This kit is analytically validated with prepared reagents.

细胞凋亡M30 Apoptosense® ELISA试剂盒细胞凋亡M30 Apoptosense® ELISA试剂盒

M30 Apoptosense® ELISA


 


 

◆原理

 

M30 Apoptosense® ELISA是PEVIVA最畅销的产品。可用于定量检测表达角蛋白18(K18)细胞(人)的凋亡情况。检测结果可信度高,检测结果重复性好。特异性检测可信度高是因为M30 Apoptosense® ELISA 只单独检测可溶性caspase-cleaved 角蛋白18(细胞凋亡产物)。

该产品广泛运用于肝脏疾病,肿瘤,毒理学等研究领域。

M30 Apoptosense® ELISA可用于检测人血清,并且带有CE标记(可用于体外诊断)。所有试剂都是即用型的。

细胞凋亡M30 Apoptosense® ELISA试剂盒



◆优点特色


特异性定量检测表达角蛋白18细胞的细胞凋亡包括肝细胞,乳腺癌、肺癌、前列腺癌、结肠癌等上皮细胞来源的肿瘤细胞。

●  可用于早期凋亡研究,比常规的Annexin V检测灵敏度高。可检测血清、血浆和细胞培养上清的样品。常规检测细胞凋亡,需要制备细胞裂解液,取材不方便。

●   可检测多种caspase介导的细胞凋亡(比如caspase-3,-7,-9)

●   夹心ELISA法进行检测,96孔板,板子可拆卸。试剂即拆即用。

●   与M65® ELISA 配套使用,定量检测细胞凋亡、细胞坏死和总细胞死亡。

●   肝脏疾病:定量检测患肝脏疾病病人的肝细胞凋亡情况,可预测患肝脏疾病的可能性。

●   肿瘤:监测上皮细胞肿瘤患者化疗诱导肿瘤细胞凋亡的情况。

●  毒理学:临床评估不同药物对肝脏细胞的毒性。

 

细胞凋亡M30 Apoptosense® ELISA试剂盒

 


 

M30 Apoptosense® 是基于M30单抗的ELISA试剂盒 (Leerset al., 1999).。 该抗体可以特异性结合caspase-cleaved 角蛋白18 (ccK18, caspase-celaved cytokeratin 18, ccCK18 或者K18-Asp396。caspase水解角蛋白18形成3个片段,其中1个片段 氨基酸第387位-第396位含有新表位(neoeptitope) ,这个片段就称为caspase-cleaved角蛋白,但是不结合天然、未切除的K18。 M30 Apoptosense® 因此可特异性检测上皮细胞的凋亡情况 (Hägget al. 2002).

 

 

◆案例应用

 

●  监测肿瘤治疗

 

人经常患的肿瘤包括肺癌,乳腺癌,前列腺癌和结肠癌。这些肿瘤细胞起源于上皮细胞,并且表达K18。肿瘤治疗过程中肿瘤细胞发生凋亡,K18被水解后释放到细胞外和血液中。.相比较而言,其他类型细胞比如淋巴细胞化疗后细胞发生凋亡不会产生K18片段。 Caspase-cleaved CK18 因此成为理想的血液型细胞凋亡标记物。进来研究发现接受不同治疗方案的肿瘤患者,其血清中的caspase-cleaved K18 (ccK18, K18Asp396-NE 或者 M30新表位)有所提高 (Krameret al., 2004Krameret al., 2006)。这个提升与临床治疗有关。 (Olofssonet al., 2007Scottet al., 2009Houet al., 2009).

 

 

肝脏疾病

 

肝细胞表达K18。在涉及细胞凋亡的肝脏疾病比如肝纤维化、肝脏损伤中K18发生水解,导致组织中M30表位暴露 (Bantel et al. 2001)。患有肝细胞凋亡相关的疾病包括丙肝病毒感染(Bantel et al., 2004),乙肝病毒感染(Papatheodoridis et al., 2008),非酒精的脂肪肝(NASH)(Wieckowska et al. 2006),毒剂相关脂肪肝(NASH)(Cave et al., 2010),胆道炎症和严重胆汁郁结 (Yagmur et al., 2007)的患者,其血液循环中可溶性caspase-cleaved K18-Asp396片段升高。 

 

 

其他运用

 

由细胞凋亡引起细胞死亡的其他疾病。检测caspase-cleaved K18片段证实可用于严重白血病患者的早期预测(Hofer et al., 2009).

 M30 Apoptosense® ELISA 可用于监测器官移植的病人(Luft et al., 2007) ,也可用于肝脏移植期间caspase抑制剂的临床实验 (Baskin‑Bey et al., 2007).

Shibayagi 胰高血糖素样肽-1(GLP-1)(活性) ELISA试剂盒

Shibayagi 胰高血糖素样肽-1(GLP-1)(活性) ELISA试剂盒

胰高血糖素样肽-1(Glucagon-like peptide-1,GLP-1)是胰高血糖素前驱体的一部分。胰高血糖素前驱体于胰脏、小肠下部以及下丘脑中表达。该前驱体的构造中含有与糖代谢有关的各种各样的生理活性物质(胰高血糖素,肠高血糖素,胃泌酸调节素,GLP-1,GLP-2)的氨基酸序列。根据表达部位加工酶的特异性,胰脏主要分泌胰高血糖素,而小肠下部主要分泌肠高血糖素和胃泌酸调节素。GLP-1和GLP-2则存在于胰高血糖素前驱体后半的结构中。GLP-1由37个氨基酸组成,有2种生物活性形式,分别为GLP-1(7-37)和GLP-1 (7-36)酰胺。两者都存在于小肠下部、胰脏和下丘脑中,GLP-1(7-36)酰胺在下丘脑中占免疫反应GLP-1(IR-GLP-1)总量的55-94%,在小肠中占27-73%。但在胰脏中只有极少量存在。大部分哺乳类(如人类、大鼠、小鼠、牛、猪、狗等)的GLP-1结构相似。

 

GLP-1: hdeferhaegtftsdvssylegqaakefiawlvkgrg  

GLP 1(7-37): haegtftsdvssylegqaakefiawlvkgrg

GLP 1(7-36) amide: haegtftsdvssylegqaakefiawlvkgr-NH2

 

GLP-1与小肠上部分泌的GIP统称为肠促胰素。该类激素是葡萄糖浓度依赖性方式促进胰岛素分泌。同时具有抑制胃肠道蠕动和胃液分泌、抑制胰高血糖素的释放、促进生长抑素的分泌、使食欲减退,促进肠上皮细胞生长、以及外周组织促进非胰岛素依赖性的葡萄糖的消耗,并促进细胞的生长的作用。有报告指出该类激素与垂体激素的分泌也有关系。

GLP-1(7-36)酰胺在生物体内代谢迅速,DPP-IV (dipeptidyl peptidase IV )会使其失去N-末端的两个氨基酸变为GLP-1(9-36)酰胺,GLP-1(7-37)变为GLP-1(9-37)后会失去活性。有报告指出,体外实验中,在犬的血浆中GLP-1(7-36)酰胺的半衰期是为61±9分,GLP-1(7-37)为132±16分。因此GLP-1的测定,取样的时候有必要使用DPP-IV抑制剂。

此外,肠促胰素中的GIP则是最有力促进GLP-1分泌的激素。回肠中GLP-1的分泌不是食物直接刺激肠道而产生的,而是由于胆碱能和肽类的刺激所产生的。

Adiponectin(脂联素)是脂肪细胞分泌的一种细胞因子。作为脂肪细胞因子,控制脂肪代谢和胰岛素感受性、是抗糖尿病、抗动脉粥样硬化、抗炎症的重要物质。血液中的脂联素通过聚集单聚体形成3聚体、6聚体或者是12-18聚体。三聚体(LMW)通过胶原三螺旋链的非共价相互作用以及球状体C1q域的疏水相互作用形成。三聚体聚集形成六聚体(MMW)或者更大的多聚体(HMW)。

Adiponectin与各种各样的生长因子相结合有明显的亲和性,将其隔离能影响细胞的生长、血管新生和细胞组织的重建。血液中HMW的测定值除了表示总脂联素以外,同时明确地反映出BMI和性别、体重减轻的影响、糖耐量、肝脏的胰岛素感受性、代谢综合征和2型糖尿病。预计HMW的测定比起总脂联素的测定,对于代谢综合征和DM2的分析更有帮助。

Shibayagi的此款试剂盒只用于测定高分子Adiponectin。
