Swiss Prot: Q9EP73Gene ID: 60533
检测原理: Acmec ELISA试剂盒采用基于双抗体夹心法的酶联免疫吸附检测技术。将抗小鼠PD-L1单克隆抗体包被在酶标板上;分别加入梯度稀释的标准品和预稀释的样本,标准品和样本中的小鼠PD-L1会与酶标板上的包被抗体充分结合;洗板后加入生物素化抗小鼠PD-L1抗体,该抗体会与板子上包被抗体捕获的标准品和样本中的小鼠PD-L1发生特异性结合;洗板后加入辣根过氧化物酶(HRP)标记的链霉亲和素,生物素与链霉亲和素会发生高强度的非共价结合;洗板后加入显色剂底物TMB,若反应孔中样品存在不同浓度的小鼠PD-L1,则HRP会使无色TMB变成不同深浅(正相关)的蓝色物质,加入终止液后反应孔会变成黄色;最后,在λmax=450 nm(OD=450 nm)处测定反应孔样品吸光度(OD),样本中的小鼠PD-L1浓度与OD成正比,通过绘制标准曲线和四参数拟合软件便可计算出样本中小鼠PD-L1的浓度。
背景说明: PD-L1, also known as B7-H1 and CD274, is an approximately 65 kDa transmembrane glycoprotein in the B7 family of immune regulatory molecules. PD-L1 is expressed on inflammatory-activated immune cells including macrophages, T cells, and B cells, keratinocytes, enothelial and intestinal epithelial cells, as well as a variety of carcinomas and melanoma. PD-L1 binds to T cell B7-1/CD80 and PD-1. It suppresses T cell activation and proliferation and induces the apoptosis of activated T cells. It plays a role in the development of immune tolerance by promoting T cell anergy and enhancing regulatory T cell development. PD-L1 favors the development of anti-inflammatory IL-10 and IL-22 producing dendritic cells and inhibits the development of Th17 cells. In cancer, PD-L1 provides resistance to T cell mediated lysis, enhances EMT, and enhances the tumorigenic function of Th22 cells.
