Protease activity determination

[Richard J. Dudley]

No kit that I know of will detect all proteases, but I think Pierce ans 
Sigma sell kits that are pretty general.  I have used FITC-labelled BSA 
and LEU-methylcoumarinamide in the past, but they are fluorometric.  
Azocoll or azocasein is colorometric.  The fluoroscent assays are 
simpler.  There are also some peptidase substrates that use 
p-nitroaniline, which absorbs at 410 nm as a free product.  I don't have 
a lot if info in fron of me, but if you e-mail me and remind me, I can 
track my folder down.
