Cat # Kit Name Probe(s) for Apoptotic Cells (Abs/Em) * Probe for Necrotic or Live Cells (Abs/Em) * Number of Assays Kit Features
V13240Single Channel Annexin V/Dead Cell Apoptosis KitAlexa Fluor 488 annexin V (495/519)SYTOX Green nucleic acid stain (504/523)

50 flow cytometry assays, each containing 2 × 105 to 1 × 106 cells in a 1 mL volume (Product Information Sheet)

Because this Alexa Fluor 488 annexin V–based assay uses only the green fluorescence channel on the flow cytometer, other parameters can be measured simultaneously using fluorescent probes with different emission spectra.
