Either measuring substrate consumption or overall production, the enzyme assays are used to monitor enzymatic activity. Provided with the required supplies and reagents for any preferred method, enzyme kinetics and inhibition studies can be successfully completed. While continuous assay sampling methods give activity readings throughout development, discontinuous techniques calculate after the reaction has been stopped. The standardized enzyme assays will provide accurate identification and measurement of the protein molecules present in samples.
Amplite® Blue Peroxidase Substrate
Supplier: AAT BIOQUEST
A variety of substrates are available for detecting peroxidase activity in ELISA assays. colourimetric HRP substrates (e.g., TMB, OPD and ABTS) have been widely used for years. Each of these substrates varies greatly with respect to its performance characteristics such as detection sensitivity, working range and attainable signal-to-noise ratios. Amplite® Blue peroxidase substrate is a soluble fluorogenic substrate for detection of peroxidase activity. Amplite® Blue allows rapid HRP detection assays to be performed with greater sensitivity than the colourimetric HRP substrates (such as TMB and OPD). The fluorescent product of Amplite® Blue does not photobleach. Amplite® Blue exhibits a flat baseline in assays, which facilitates low-level detection sensitivity and allows for high signal-to-noise ratios.

Fluorescent β-Galactosidase assay kit
Supplier: G-Biosciences
β-Galactosidase assay is for determining the β-galactosidase activity in the lysates of cells transfected with a β-galactosidase expression construct. It uses chlorophenol red-β-D-galactopyranoside (CPRG), which is up to 10 times more sensitive than the classic O-nitrophenyl-β-D-galactopyranoside (ONPG) β-Galactosidase assays. This increased sensitivity makes it simpler to measure β-galactosidase activity in cells that are difficult to transfect or have low β-galactosidase activity expression. β-Galactosidase activity is measured using a spectrophotometer or a microplate reader to determine the amount of substrate converted at 570 to 595 nm.
