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.

β-Galactosidase Assay Kit and Reagents
Supplier: Thermo Fisher Scientific
The Mammalian β-Galactosidase Assay Reagent Kit is a simple and versatile assay to measure β-galactosidase activity in cultured mammalian cells. Cells grown on a plate may be lysed and tested for β-galactosidase activity by adding a single all-in-one lysis-and-assay solution. Alternatively, M-PER™ Mammalian Protein Extraction Reagent may be used to prepare lysate from washed adherent or pelleted cells, and then a portion of the lysate used to assay for β-galactosidase activity. With M-PER Reagent, there is no need to scrape cells or to perform freeze-thaw cycles. The remaining lysates prepared with M-PER™ Reagent may be used for applications such as reporter assays (luciferase, β-galactosidase and chloramphenical acetyltransferase), protein kinase assays (PKA, PKC, and tyrosine kinase), immunoassays (Western blot, ELISA, RIA) and protein purification.

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.
