There are many assays that will measure cell death (MTT, trypan blue 
exclusion, etc..) based on membrane integrity or metabolic potential.  
Assays that measure cell death as a function of DNA fragmentation are based  
either on insitu end labeling (TUNEL) of the fragments or sorting of the 
intact DNA from the fragmentated DNA and quantifying the DNA using the 
diphenylamine method of Burton (Burton, K. 1956. Biochem. J. 62:315).  The 
second method is more cost effective and can be more reliable.  A good 
reference is, Sellins, K. and Cohen, J.J., J of Immunology, vol.139, No. 10, 
pp 3199-3206,  as well as our own, Story, M.D., Voehringer, D.W., Malone, 
C.G., Meyn, R.E., Int. J. Radiat. Biol., 1994, vol 66, no 6, 659-668.  This 
method works well on suspension cells with a little modification for adherant 
lines.  Email me if you need more help.
