Product Specification
| Usage | 1. Adjust the cell density to about 1 × 106Cells/ml. 2. Remove 0.2 ml of cell suspension from a cell culture flask (2 × 105Cells) were transferred into a clean centrifuge tube. 3. Centrifuge at 1000 g at room temperature for 5 minutes to remove the medium. 4. The cell pellet was gently resuspended with 0.2 ml of pre-cooled PBS solution. 5. Centrifuge at 1000 g for 5 minutes at room temperature to remove PBS. 6. The cell pellet was gently resuspended with 0.2 ml of pre-cooled binding buffer (component C. Binding Buffer). 7. Add 5μl Annexin V-EGFP (component A) and 5μl PI dye solution (component B), and gently mix well. 8. Incubate at room temperature (18-24 °C) for 10-15 minutes in the dark. 9. Alternatively, replenish the volume to 0.4 ml with binding buffer or PBS. 10. Place the sample on ice and protect it from light, and test it as soon as possible. 11. Use flow cytometry or fluorescence microscope for detection and analysis. | ||||||||||||||||

| Description |
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 +).
