| 產品介紹 |
磷脂酰絲氨酸（PS）是一種帶負電荷的磷脂，正常細胞中，PS只分布在細胞膜脂質雙層的內側，而在細胞凋亡早期，細胞膜 PS由脂膜內側翻向細胞膜外側，使PS暴露在細胞膜外表面。Annexin V是一種分子量為35~36kD 的Ca2+依賴性磷脂結合蛋白，與磷脂酰絲氨酸有高度親和力，故可通過細胞外側暴露的磷脂酰絲氨酸與凋亡早期細胞的胞膜結合。因此Annexin V被公認為檢測細胞早期凋亡的靈敏指標之一。 將Annexin V進行FITC標記，以標記了的Annexin V作為探針，利用熒光顯微鏡或流式細胞儀可檢測細胞凋亡的發生。碘化丙啶（Propidium Iodide, PI）是一種核酸染料，它不能透過正常細胞或早期凋亡細胞的完整的細胞膜，但對凋亡中晚期的細胞和壞死細胞，PI能夠透過細胞膜而使細胞核染紅。因此采用Annexin V與PI雙染的方法，就可以將處于不同凋亡時期的細胞區分開來。 |

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.
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.
