There are many such assays (51Cr release being such a sloppy, messy assay 
that everybody wants to get a better one.)  Unfortunately, none of the 
alternatives is as sensitive, versatile, or straightforward.  Check out 
back issue of J Immunological Methods - about every 2nd or 3rd issue has 
a new method.  Some may be preferrable to 51Cr under specific 
circumstances (i.e. if your target cell type and experimental conditions 
fit with it.)  
	One exception is using T-T hybridomas instead of CTL.  If 
youdon't need to generate CTL but only are interested in the target 
presentaion of a model antigen, these can have great advantages.
