For a live/dead assay you probably want the cells to remain as adherent as possible. I've used 0.1% Triton X-100 for 10min, or 5% DMSO for 12+ hrs.

Hi Methodologists -

I want to do a Live/Dead Assay on some HUVECs and the protocol calls for using saponin to kill control cells. I noticed it is a surfactant, can I use something like Tween-20 or Triton-X 100 instead that I have around the
lab?  Also what concentration would you use (I usually do 1% Triton to
permeate the cells)?

Thanks all,
Josh
