  • 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.

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 note it can take a day or two for updated information to refresh on the internet).

The quality of our products, kitsand datasheets is very important to us, as is any feedback and data we receive. It is regrettable that the information we had on this particular antibody was not of the standard both we and our customers expect from our products.

Should you have any further questions regarding this issue, please do not hesitate to contact me.

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 translocated from the inner cell membrane tothe cell surface.

I hope this is helpful. Please contact us again if you have any further questions.

The source of the Annexin V-PE Apoptosis Detection Kit informed me that the formulation of the buffer is confidential and therefore I am unable to compare it with the customer's home made buffer, I'm very sorry. The customer can buy more of the buffer which is reference ab14084. https://www.abcam.com/index.html?datasheet=14084 I hope this will help,
