  • Product overview

    Annexin V-PE Apoptosis Staining / Detection Kit (ab14155) is based on the observation that soon after initiating apoptosis, most cell types translocate the membrane phospholipid phosphatidylserine (PS) from the inner face of the plasma membrane to the cell surface. Once on the cell surface, PS can be easily detected by staining with a fluorescent conjugate of Annexin V, a protein that has a strong natural affinity for PS. The one-step staining procedure takes only 10 minutes. In addition, the assay can be directly performed on live cells, without the need for fixation.

  • Tested applicationsSuitable for: FM, Flow Cytmore details


  • FunctionThis protein is an anticoagulant protein that acts as an indirect inhibitor of the thromboplastin-specific complex, which is involved in the blood coagulation cascade.
  • Involvement in diseasePregnancy loss, recurrent, 3
  • Sequence similaritiesBelongs to the annexin family.
    Contains 4 annexin repeats.
  • DomainThe [IL]-x-C-x-x-[DE] motif is a proposed target motif for cysteine S-nitrosylation mediated by the iNOS-S100A8/A9 transnitrosylase complex.
    A pair of annexin repeats may form one binding site for calcium and phospholipid.
  • Post-translational
    S-nitrosylation is induced by interferon-gamma and oxidatively-modified low-densitity lipoprotein (LDL(ox)) possibly implicating the iNOS-S100A8/9 transnitrosylase complex.

Thank you for your enquiry.

I have investigated our records for ab14155. I can confirm that this kit contains Annexin V-PE.

The datasheet has been updated with the correct information and I apologize for any confusion. (Please not...

Thanks for your enquiry.

The reagent that comes with this kit is not an antibody. It is PE/Cy5-labeled Annexin V protein. Annexin V will bind specifically to the membrane phospholipid phosphatidylserine, which in apoptotic cells has transloca...
