{"product_id":"20393","title":"Enterokinase Activity Assay Kit _ 20393ES","description":"\u003cp\u003eEnterokinase (also known as enteropeptidase, EC 3.4.21.9) is a key enzyme that initiates protein digestion in the intestine. It precisely activates trypsinogen to trypsin, which then cascade-activates chymotrypsinogen and procarboxypeptidase. Its expression is specifically localized in differentiated intestinal cells and goblet cells, making it both a core regulator of nutritional digestion and a reliable marker of intestinal epithelial maturation.\n\u003cbr\u003eThe Enterokinase Activity Assay Kit is a rapid method for determining enterokinase activity in biological samples. This method detects enterokinase activity by cleaving a 7-amino-4-trifluoromethylcoumarin (AFC)-labeled peptide substrate containing an enterokinase recognition sequence. The intensity of the fluorescent product AFC (excitation wavelength Ex=380 nm, emission wavelength Em=500 nm) generated by the reaction is proportional to the enzyme activity in the sample.\u003c\/p\u003e","brand":"Yeasen","offers":[{"title":"100 T","offer_id":54250651877694,"sku":"20393ES60","price":1000.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.yeasenbio.com\/nl\/products\/20393","provider":"Yeasen - Leading Innovation in Molecular Enzymes and Reagents","version":"1.0","type":"link"}
