Hello Alison,

The following basic procedure produces an apoptotic population:

1]  Maintain Jurkat cells in RPMI 1640 medium with 10% FCS, 2mM
2]  Set up 12 x 75 mm tubes with 10e6 cells/ml
3]  Add anti-CD95 [100 ng/ml] antibody and incubate for 2 to 4 H at

 CD95 antibody - clone CH-11

More details are available in:
Mc Closkey et al, Flow Cytometric Detection and Quantification of
Apoptotic Cells which is in the Manual of Molecular and Clinical
Laboratory Immunology, 2006.  

Good luck,

Hi all,
I am trying to establish a positive control for an apoptosis assay using
annexin-V and 7-AAD. So far i have been using Camptothecin, but have
only been getting small numbers of apoptotic cells.  Does anyone have a
good protocol for apoptosis induction using camptothecin? i.e.
concentration, time period of incubation etc.
