Enzyme assay - Wikipedia
Enzyme assays are laboratory methods for measuring enzymatic activity. They are vital for the study of enzyme kinetics and enzyme inhibition.
Enzyme assays - ScienceDirect
2014年5月1日 · Enzyme assays are performed to serve two different purposes: (i) to identify a special enzyme, to prove its presence or absence in a distinct specimen, like an organism or a tissue and (ii) to determine the amount of the enzyme in the sample.
Enzyme Assay - an overview | ScienceDirect Topics
Enzyme assays represent an important tool for screening of sample libraries in context of drug discovery. In addition, enzyme assays are valuable for diagnosis of several diseases in clinical settings due to their high sensitivity, specificity, and rapid response.
Methods of Measuring Enzyme Activity Ex vivo and In vivo
Fluorescence quenching and Förster (or “fluorescence”) resonance energy transfer, commonly known as FRET, have been used to visualize enzyme activity by connecting a pair of chemical species by a chemical linker that can be broken, e.g., by a hydrolytic enzyme.
