Hi Hewa Dikkumburage Tharindu Madhuranga

If I got your question well, then I suggest to use FITC-Annexin V kit.

Best....

Another simple one is esterase cleavage of Calcein-AM to calcein (0.5-2 h in PBS), which you can also co-run with uptake of ethidium bromide. There are numerous kits avail., but buying the individual reagents is cheapest.

Dear sir, @Mohamed Khashan @Thomas J Raub,
