Apoptosis, or programmed cell death, is a vital biological process that maintains cellular homeostasis by eliminating damaged or unwanted cells. Accurate detection of apoptosis is important in areas such as cancer research, drug development, and immunology. One of the most widely used methods for apoptosis detection is the Annexin V assay, which enables precise quantification and analysis of apoptotic cells.
During early apoptosis, a key hallmark is the translocation of phosphatidylserine (PS) from the inner to the outer leaflet of the cell membrane. Annexin V, a protein with a high affinity for phosphatidylserine, is commonly used to detect this process. When labeled with fluorophores, Annexin V can bind to exposed PS, allowing for visualization and quantification of apoptotic cells through flow cytometry or other fluorescence-based methods.
In addition to Annexin V binding, many apoptosis assays include a secondary dye, such as propidium iodide (PI) or 7-AAD, to distinguish between early apoptotic and late apoptotic/necrotic cells. This combination ensures a comprehensive analysis of cell viability:
This dual-staining approach provides a clear and detailed picture of cell populations, enabling researchers to assess apoptosis with high specificity and sensitivity.
Reddot Biotech offers a range of high-quality Annexin V-based apoptosis detection kits, each optimized for specific research needs. These kits use different fluorophores to suit various experimental setups and flow cytometry configurations.
Annexin V apoptosis detection kits are widely used in areas including:
Selecting the appropriate apoptosis detection kit depends on your experimental requirements, including the availability of flow cytometry channels and the desired fluorescence characteristics. For standard green fluorescence, the Annexin V-FITC or Alexa Fluor 488 kits are excellent choices. For experiments requiring reduced spectral overlap or far-red detection, the Alexa Fluor 647 kit provides optimal performance.
