背景

Annexin V is a cellular protein, which plays important roles in the inhibition of the activity of phospholipase A1 and blood coagulation by competing for phosphatidylserine (PS) binding sites with prothrombin. Annexin V has a high affinity to PS and is used as a probe to detect cells that have expressed PS on the cell surface. After initiating apoptosis, cells translocate phosphatidylserine (PS) from the inner face of the plasma membrane to the cell surface soon, which can be easily detected by Annexin V.

 Annexin V-FITC Apoptosis Detection Kit uses a fluorescent conjugate of Annexin V that can easily detect PS on the cell surface after initiating apoptosis. The one-step staining procedure needs only 10 minutes. The result can be analyzed by fluorescence microscopy or by flow cytometry. The Annexin V-FITC Apoptosis Detection Kit can differentiate apoptosis vs necrosis when performing both Annexin V-FITC and PI staining.

Description

Annexin V是一种Ca2+依赖性磷脂结合蛋白,可与磷脂酰丝氨酸(Phosphatidylserine, PS)特异结合。PS正常位于细胞膜脂质双层的内侧,但在细胞凋亡早期PS可从细胞膜的内侧翻转到细胞膜的外表面,暴露在细胞外环境中。Annexin V对PS具有高亲和力,对Annexin V进行荧光素(FITC)标记,以带有标记的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,染色过程仅需10-20分钟。碘化丙啶(Propidium Iodide, PI)可与双链DNA特异性结合产生红色荧光,正常情况下无法透过细胞膜。但在凋亡晚期的细胞和死细胞,PI能够透过细胞膜而使细胞核染色。当同时进行Annexin V-FITC和PI染色时可区分处于不同凋亡时期的细胞及死细胞。
