Dear all We have been using a anti-Caspase-3 rabbit polyclonal ab conjugated with PE (this is supposed to bind to the active form only) by flow. We've looked for caspase-3 activation in camptothecin or etoposide treated Jurkatt cells (cytospins confirm apoptosis in these cells) after fixation and perm, without success. This ab is from Pharmingen. Does anyone have experience with looking for caspase-3 activation by flow ? Are there other antibodies available ? Any comments would be much appreciated.
