A carrier having at least one kinetics and fluorescence enhancing support and a dry substance selected from the group consisting of fluorogenic substrates, B-methylumbelliferone, 7-amino-4-methyl coumarin, B-napthylamine, fluoroscein, and resorufin deposited on the support demonstrates substantial enhancement of hydrolysis kinetics and fluorescence over pure liquid systems. When the device has a plurality of supports and the supports have different fluorogenic substrates an enzyme rate-of-reaction profile representative of a microorganism in the suspension can be determined and used to identify the organism. The device can also be used to characterize enzymes expressed by other biological specimens.
一种载体具有至少一种动力学和荧光增强支持物,以及一种选自含氟底物、B-甲基伞形酮、7-氨基-4-甲基香豆素、B-萘胺、荧光素和resorufin 所组成的组的干物质,沉积在支持物上,与纯液体系统相比,该载体的水解动力学和荧光得到了极大的增强。当该装置具有多个支持物,且支持物具有不同的荧光底物时,可确定悬浮液中微生物的酶反应速率曲线,并用于识别该微生物。该装置还可用于鉴定其他生物样本表达的酶。
