Dear all,
I need your comments to settle a discussion in the lab regarding PI-based gating of viable 
cells in FL3. I do membrane staining with a combination of FITC and PE conjugated 
Moabs, then I stain cels with PI, make exclusion gate on PI-positive cells in FL3 and then 
evaluate FL1/FL2 staing on PI-negative cells. Is that a correct approach and if not what are 
other ways?
Thank you,
Karolina Palucka
