Apoptosis is the process of cell self-destruction during normal development. It is prevalent in cell types with a limited lifespan. The problem of regulation of apoptosis is thought to be associated with many diseases. Therefore, apoptosis detection has become a key target in many related research areas.
Apoptosis is a multi-step process. A wide range of apoptosis assays are available for early, intermediate and late cellular events. Creative Biolabs offers a wide range of apoptosis assays including Annexin V binding assay, caspase activity assays, mitochondrial membrane potential assays, DNA fragmentation and morphology.
We provide a general protocol for Annexin V binding assays for apoptosis. This provides a rapid and reliable assay for apoptosis. And these protocols and troubleshooting are useful for flow cytometry or fluorescence microscopy to assess apoptosis.
|Stages||Solutions and Reagents|
|Cell Seeding||Phosphate buffer (PBS), media, binding buffer|
|Reagent Treatment||Apoptosis reagent, Annexin V incubation reagent, binding buffer|
Collect the cells and wash them. Then dilute the cells to prepare a cell suspension of appropriate concentration. Finally, add the cells and media to a 96-well plate and incubate overnight.
Prepare apoptosis reagent. Remove the cell plate from the incubator and aspirate the growth medium. Set up the treatment and control groups in the wells of the 96-well plate, and add the prepared apoptosis reagent respectively.
Prepare Annexin V incubation reagent. Add the reagent to the wells and incubate in the dark at room temperature.
Use flow cytometry to analyze cells without washing them.
This is a simple experimental protocol. However, there are still some details that need to be paid attention to during the operation. We provide frequently asked questions and their solutions that you can refer to. Please note that you should always use the protocol provided in the data sheet when using a specific kit.

Apoptosis is detected by staining cells with Annexin V and propidium iodide solution followed by flow cytometry analysis. This is a simple and rapid method of apoptosis detection. If you need protocols for other apoptosis assays or related products and services, please feel free to contact us.
