This invention relates to enzyme assays and substrates for use in such assays. The presence or absence of certain enzymes in vivo is a useful indicator of illness or deficiency in the organisms concerned. Enzymes are also useful in monitoring microbial growth in fermentors and in the food industry and are important in enzyme-linked immunosorbent assays (ELISA), and in the characterization of bacterial species in culture. Disclosed is a reagent for enzyme assay comprising a substrate consonant with a given enzyme to be assayed, labelled with a chromogenic group which, on action of the given enzyme, is liberated to give a colored product. Also disclosed is a kit for the assay of an enzyme comprising the reagent of the disclosed invention.
本发明涉及酶测定和用于此类测定的底物。在体内存在或不存在某些酶是指示有机体疾病或缺陷的有用指标。酶也在发酵罐中监测微
生物生长以及在食品工业中使用,并且在酶联免疫吸附测定(ELI
SA)和细菌种类的表征中非常重要。本发明揭示了一种用于酶测定的试剂,包括与待测酶相符的底物,标记有色团,该色团在待测酶的作用下被释放出来形成彩色产物。还揭示了一种用于测定酶的试剂盒,包括本发明的试剂。
