WebVarious enzymes, especially liver enzymes such as aminotransferases (AST and ALT), can be measured by coupled enzymatic reactions. For example, AST converts 2-oxoglutarate into L-glutamate and at the same time converts L-aspartate into oxaloacetate. Webmeasuring enzyme activity is normally to determine the amount of enzyme present under defined conditions, so that activity can be compared between one sample and another, …
WebThe ALT Activity Assay Kit provides a simple and direct procedure for measuring ALT activity in a variety of biological samples. Preparation Instructions ALT activity is determined by a coupled enzyme assay, which results in a colorimetric (570 nm)/fluorometric ( ex = 535/ em = 587 nm) product, proportional to the pyruvate generated.
