Annexin V-EGFP/PI cell apoptosis detection kit uses EGFP-labeled Annexin V as a probe to detect the occurrence of early cell apoptosis. The detection principle is: in normal living cells, phosphotidylserine (PS) is located on the inside of the cell membrane, but in early apoptotic cells, PS flips from the inside of the cell membrane to the surface of the cell membrane and is exposed to the extracellular environment. Annexin-V (Annexin-V) is a Ca2 +-dependent phospholipid binding protein with a molecular weight of 35-36KD, which can bind to PS with high affinity. It can bind to the cell membrane of early apoptotic cells through phosphatidylserine exposed on the outside of the cell. In addition, Propidium Iodide (PI) is also provided in this kit to distinguish surviving early cells from necrotic or late apoptotic cells. PI is a nucleic acid dye that cannot penetrate the intact cell membrane of normal cells or early apoptotic cells, but can penetrate the cell membrane of late apoptotic and necrotic cells to make the nucleus red. Therefore, when Annexin V is used in combination with PI, PI is excluded from viable cells (Annexin V-/PI-) and early apoptotic cells (Annexin V +/PI-), while late apoptotic cells and necrotic cells are stained double positive by EGFP and PI combination (Annexin V +/PI +).
