Protocol for Apoptosis Assay by Flow Cytometry Using Annexin V Staining Method

Authors: Imayavaramban Lakshmanan and Surinder K Batra, date: 03/20/2013, view: 27376, Q&A: 1

This assay is used to count the number of cells that have undergone apoptosis. Apoptosis will be detected by initially staining the cells with Annexin V and propidium iodide solution followed by flow cytometry analysis. It is based on the principle ...

Hi, I'm using this Annexin-V-FLUOS staining kit and according to the protocol prepared by Roche, 100 ul of mixture(incubation buffer+annexin-V+PI) should be mixed with 1 million of cells. Does this number represent the initial amount of cells that have been seeded or for the ones that would be harvested?
Second question; how will the percentages be affected if I use less amount of staining mixture?

Thank you.

Yes. It represents the initial amount of cells that have been seeded

Second question; how will the percentages be affected if I use less amount of staining mixture?

For us it has worked very well for the mentioned concentration, if you want to use less amount of staining solution, we would recommend seeding less number of cells.
