L-Argininamide, N-[(1,1-dimethylethoxy)carbonyl]-L-leucylglycyl-N-(4-nitrophenyl)-, monoacetate (9CI)

Biological Activity

Boc-LGR-pNA is a chromogenic substrate for the detection of bacterial endotoxins.1 Upon enzymatic cleavage by endotoxin-induced amidases, p-nitroanilide (pNA) is released which can be quantified by colorimetric detection at 405 nm as a measure of endotoxin levels.
