产品介绍磷脂酰丝氨酸(PS)是一种带负电荷的磷脂,正常细胞中,PS只分布在细胞膜脂质双层的内侧,而在细胞凋亡早期,细胞膜 PS由脂膜内侧翻向细胞膜外侧,使PS暴露在细胞膜外表面。Annexin V是一种分子量为35~36kD 的Ca2+依赖性磷脂结合蛋白,与磷脂酰丝氨酸有高度亲和力,故可通过细胞外侧暴露的磷脂酰丝氨酸与凋亡早期细胞的胞膜结合。因此Annexin V被公认为检测细胞早期凋亡的灵敏指标之一。
   将Annexin V进行FITC标记,以标记了的Annexin V作为探针,利用荧光显微镜或流式细胞仪可检测细胞凋亡的发生。碘化丙啶(Propidium Iodide, PI)是一种核酸染料,它不能透过正常细胞或早期凋亡细胞的完整的细胞膜,但对凋亡中晚期的细胞和坏死细胞,PI能够透过细胞膜而使细胞核染红。因此采用Annexin V与PI双染的方法,就可以将处于不同凋亡时期的细胞区分开来。

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. Propidium Iodide (PI) is a standard flow cytometric viability probe and is used to distinguish viable from nonviable cells. Viable cells with intact membranes exclude PI, whereas the membranes of dead and damaged cells are permeable to PI. Cells that stain positive for FITC Annexin V and negative for PI are undergoing apoptosis. Cells that stain positive for both FITC Annexin V and PI are either in the end stage of apoptosis, are undergoing necrosis, or are already dead.

Jurkat cells (T-cell leukemia,human) treated with 10 μM of camptothecin for 4 hours(panel right) or untreated control(panel left).
1. Wash cells twice with cold PBS and then resuspend cells in 1×Binding Buffer at a concentration of 1×106 cells/ml.
2. Transfer 100 μl of the solution (1×105cells) to a 5 ml culture tube.
3. Add 5 μl of Annexin V-FITC.
4. Add 5 μl PI.
5. Gently vortex the cells and incubate for 15 min at RT (25°C) in the dark.
6. Add 400 μl of 1×Binding Buffer to each tube.Analyze by flow cytometry within 1 hr.
