A method and device for the assay of alkaline phosphatase in dairy products. A sample of the dairy product is added to a self-indicating fluorometric substrate comprising a single orthophosphoric ester on a phenolic ring. After hydrolysis of the phosphate radical by the alkaline phosphatase in the sample, the substrate and the sample added thereto are exposed to electromagnetic radiation at a first wavelength. The increase in fluorescence at a second wavelength produced by the hydrolysis of the phosphate radical by the alkaline phosphatase is determined. This increase is linearly related to the activity of alkaline phosphatase present in the sample of the dairy product.
一种检测乳制品中碱性磷酸酶的方法和装置。将乳制品样品添加到由酚醛环上的单个正磷酸酯组成的自指示荧光测定底物中。样品中的碱性磷酸酶水解磷酸自由基后,将基质和加入其中的样品置于第一波长的电磁辐射下。测定碱性磷酸酶水解磷酸基所产生的第二波长荧光增加量。这种增加与乳制品样品中存在的碱性磷酸酶的活性成线性关系。
