  • General notes

    Annexin V/ANXA5-Cy3 Apoptosis Detection Reagent ab14143 can be used in a 10 min, one-step staining procedure to detect apoptosis by staining phosphatidylserine molecules which have translocated to the outside of the cell membrane. Analysis is by flow cytometry or fluorescence microscopy.

    This Annexin V/ANXA5-Cy3 reagent can be used with Annexin V/ANXA5 binding buffer ab14084 (see protocol section for instructions). The Annexin V/ANXA5-Cy3 reagent is also available as part of Annexin V/ANXA5-Cy3 apoptosis kit ab14142 and Annexin V/ANXA5-Cy3 with SYTOX apoptosis kit ab14144.

    For more apoptosis assays, review the full set of Annexin V/ANXA5 assays, or the apoptosis assay and apoptosis marker guide.
