  • Product overview

    Annexin V-Biotin Apoptosis Staining / Detection Kit (ab1419) 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 easily bind to Biotin-conjugated Annexin V, a protein that has a strong natural affinity for PS. Annexin V-Biotin can be detected in conjunction with conventional dye-staining using any streptavidine- or avidin-dye reagents, such as (strept)avidine-fluorescein, -peroxidase, -alkaline phosphatase (AP), and -beta-gal, etc.

Customer reviews and Q&As

Thank you very much for contacting us with your question.

We unfortunately do not sell the streptavidin-FITC to use with this kit, however we do have streptavidin-HRP available (ab7403). Would this be suitable for you?

Thank you for your enquiry. Annexin V staining is calcium dependent, therefore all buffers used after the annexin V staining step should contain calcium (1.8-2.5 mM). Fluorescence will fade gradually under the light, therefore any experiments pe...

The incubation time can be extended to 30 min. However, a longer incubation period can sometimes result in more dead cells, which can give false positive results. Generally you should limit it to 10 min. After incubation, you can put the cells on ice i...
