BETA-GLUCOSIDASE ACTIVITY ASSAY KIT

Not available outside of the UK & Ireland.

Application

β-Glucosidase Activity Assay Kit has been used to measure the β-glucosidase activity of the sample.

Features and Benefits

Compatible with high-throughput handling systems.

General description

β-Glucosidase hydrolyzes carbohydrates by acting on terminal, non-reducing b(1→4)-linked D-glucose residues with the release of D-glucose. β-Glucosidases are required by organisms for the consumption of cellulose. Lysozyme, a β-glucosidase present in tears, acts on the β(1→4) glucose bonds present in the peptidoglycan cell wall of Gram-negative bacteria and helps to prevent bacterial infections in the eye. Defects in β-glucosidase activity have been implicated in Gaucher′s disease and Parkinson′s disease.

Principle

In this assay, β-glucosidase activity is determined by a reaction in which β-glucosidase hydrolyzes p-nitrophenyl-β-D-glucopyranoside resulting in the formation of a colorimetric (405 nm) product, proportional to the β-glucosidase activity present. One unit of β-Glucosidse is the amount of enzyme that catalyzes the hydrolysis of 1.0 µmole substrate per minute at pH 7.0.

Suitability

The β-Glucosidase Activity Assay kit provides a simple and direct procedure for measuring β-glucosidase activity in biological samples, for characterizing β-glucosidase production, and for the screening of β-glucosidase modulators.
