产品介绍:Annexins are a family of structurally related proteins that can bind specifically to cellular membranes (Cruetz, 1992). Annexin V has anticoagulant activity and is a monomer with a molecular weight of 35.8 kDa (Maurer-Fogy, 1989). It has a very high affinity for membranes containing the negatively charged phospholipid phosphatidylserine (PS). Specific binding is rapid and calcium-dependent. Its equilibrium dissociation constant is about 10-10 M in the presence of >1.5 mM Ca2+ (Andree, 1990), and specific binding is abolished if the Ca2+ is chelated by EDTA.Annexin-V是一种分子量为35~36KD的Ca2+依赖性磷脂结合蛋白,能与PS高亲和力特异性结合。将Annexin-V进行荧光素(FITC、PE)或biotin标记,以标记了的Annexin-V作为荧光探针,利用流式细胞仪或荧光显微镜可检测细胞凋亡的发生。其意义:检测早期凋亡的细胞,同时可区分活细胞和坏死细胞磷脂酰丝氨酸(Phosphatidylserine,PS)正常位于细胞膜的内侧,但在细胞凋亡的早期,PS可从细胞膜的内侧翻转到细胞膜的表面,暴露在细胞外环境中。碘化丙啶(propidine iodide,PI)是一种核酸染料,它不能透过完整的细胞膜,但在凋亡中晚期的细胞和死细胞,PI能够透过细胞膜而使细胞核红染。因此将Annexin-V与PI匹配使用,就可以将凋亡早晚期的细胞以及死细胞区分开来。
