Description
In normal cells, phosphatidylserine (PS) is located only on the inner side of the lipid bilayer of the cell membrane. However, in the early stages of apoptosis, phosphatidylserine (PS) flips from the inner side to the outer side of the lipid bilayer. Annexin V is a 35-36 kDa Ca²⁺-dependent phospholipid-binding protein with a high affinity for phosphatidylserine. Therefore, it can bind to the cell membrane of early apoptotic cells through the exposed phosphatidylserine on the outer side of the cell. As a result, Annexin V is used as a sensitive marker for detecting early apoptosis. When Annexin V is labeled with the fluorescent dye sFluor488, the labeled Annexin V serves as a fluorescent probe. The occurrence of apoptosis can be detected using a fluorescence microscope or flow cytometer.
This kit is suitable for detecting apoptosis in cultured cells (not recommended for detecting tissue samples).
Components
- AnnexinV-sFluor488
- Propidium iodide Dye
- Binding Buffer
Additional Notes
- Annexin V-sFluor488 components should be aliquoted as needed and stored at -20°C, avoiding repeated freeze-thaw cycles.
- Propidium iodide and Binding Buffer components can be stored at 4°C when not in use. Propidium iodide should be protected from light.
- Before using micro-reagents, please centrifuge to collect the liquid.
- Propidium iodide (PI) is toxic. Please wear gloves when handling it.
- This kit is suitable for detecting live cells. When using a flow cytometer, the cell count should not be lower than 1x105. It is not recommended for detecting tissue samples.
- Suspension-cultured cells are recommended. For adherent cells, use trypsin without EDTA for digestion. Improper digestion may cause false positives, and using a cell scraper may lead to cell clumping, affecting detection. Cells digested with trypsin can be stored in PBS containing 2% BSA to prevent further damage.
- Fixation of cells may cause fluorescence quenching; please do not fix the samples.
- Due to variations in cell types, apoptosis inducers, and detection instruments, fluorescence compensation for flow cytometry may vary. Therefore, it is recommended to use cells treated with apoptosis inducers as controls for fluorescence compensation adjustment in each experiment.
Storage
Store at 2-8°C for 12 months, protected from light.
