If the question is "what agent effectively induces apoptosis in HL-60?",
then the answer is that a 4-5 hour treatment with camptothecin is very
effective.  40-80% will be in apoptosis in this time frame.  Cam can be
purchased fairly cheaply from Sigma (IIRC).

PS, I normally wouldn't have bothered the list with this reply, but with
no text before the @ I am assuming your return address isn't real.
