Apoptosis & Necrosis Assay (Flow Cytometry)
Detect compound induced cell death using Cyprotex’s flow cytometric apoptosis and necrosis assay.
Cyprotex delivers consistent, high quality data with the flexibility to adapt protocols based on specific customer requirements.
Introduction
Background information:
- Flow cytometry allows analysis of multiple parameters of cell health and provides a high throughput analysis of compound cytotoxicity.
- Apoptosis and necrosis occur during cell death in response to cytotoxic conditions. Cyprotex’s apoptosis and necrosis assay utilizes Annexin V and propidium iodide dual staining to monitor cellular death.
- Annexin V-FITC binds to phosphatidylserine which is translocated from the inner to outer plasma membrane during early apoptosis. Propidium Iodide is a cell impermeable nuclear dye which is excluded by viable and early apoptotic cells. However, it is taken up by necrotic or late apoptotic cells resulting in red fluorescence.
- A dose dependent increase in apoptotic or necrotic cells, accompanied by a decrease in live cells, indicates a compound is inducing cellular death.
