In-gel digesters:
Would anyone have a US source for
N-(alpha)-benzoyl-DL-lysine-p-nitroaniline (most likely hydrobromide)?
It's available from WAKO but not stocked in the US, thus at least a 3wk
delay they say.
Bachem and Sigma come up empty as does Calbiochem, altho Calbiochem has
N-(alpha)-Boc-L-lysine-thiobenzyl ester which would presumably serve as a
substrate for Lys-C, but without knowing the relative rates of the two
substrates I'd prefer to stick with what WAKO standardizes their preps with.
Thanks,
