{"product_id":"20373","title":"Carboxypeptidase B Activity Assay Kit _ 20373ES","description":"\u003cp\u003eCarboxypeptidase B (also known as peptidyl-L-lysine (L-lysine) hydrolase, arginase carboxypeptidase, EC 3.4.17.2) specifically hydrolyzes C-terminal basic amino acids of proteins, including lysine (Lys, K), arginine (Arg, R), and histidine (His, H).\n\u003cbr\u003eThe Carboxypeptidase B Activity Assay Kit achieves detection through the following mechanism: after enzymatic cleavage of the substrate Hippuryl-L-Arg (Cat#20819ES) containing a specific recognition site, the product produces a characteristic absorbance at 254 nm wavelength; within a certain concentration range, the rate of change in absorbance at 254 nm is positively correlated with enzyme activity, allowing direct quantification of carboxypeptidase B catalytic activity.\n\u003cbr\u003eThe Carboxypeptidase B Activity Assay Kit is a colorimetric-based dedicated detection tool for carboxypeptidase B activity, designed to provide rapid and accurate activity quantification for enzyme preparation R\u0026amp;D, production quality control, and applied research.\u003c\/p\u003e","brand":"Yeasen","offers":[{"title":"20 T","offer_id":54250645684542,"sku":"20373ES20","price":500.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.yeasenbio.com\/ru\/products\/20373","provider":"Yeasen - Leading Innovation in Molecular Enzymes and Reagents","version":"1.0","type":"link"}
