Boc-LRR-AMC is a fluorogenic substrate for the trypsin-like activity of the 26S proteasome or 20S proteolytic core. Upon enzymatic cleavage by the 26S proteasome or 20S proteolytic core, amino-4-methylcoumarin (AMC) is released and its fluorescence can be used to quantify 26S proteasome or 20S proteolytic core trypsin-like activity. AMC displays excitation/emission maxima of 340-360/440-460 nm, respectively.
CRA-2059 hydrochloride is a highly specific and selective tryptase inhibitor, with a Ki of 620 pM for recombinant human tryptase-β (rHTβ)[1][2].
Tryptase is a trypsin-like serine protease found as a major protein component in human mast cell secretory granules. CRA-2059 hydrochloride has the potential for inflammatory bowel disease research[1].
