Viability detections are based on properties of living cells such as endocytosis, enzymatic activity, cell membrane integrity or proliferation. Since each method has weaknesses, fluorescent double staining is sometimes used to simultaneously detect apoptosis and necrosis, such as vital fluorescence double staining with propidium iodide (PI) like and Annexin V. Double stained cells with Annexin V and PI indicate dead cells, while single PI stained cells are classified as necrotic and single Annexin V stained cells as apoptotic. Browse our Annexin V kits down below and combine them with propidium iodide (
