General description

Glutamate oxidase is an oxidoreductase that catalyzes the oxidative deamination of L-glutamate to ketoglutarate, ammonia, and hydrogen peroxide.

The Glutamate Oxidase Assay Kit provides a simple and direct procedure for measuring glutamate oxidase activity in a variety of samples such as solutions and cell extracts. Glutamate Oxidase activity is determined by a coupled enzyme assay, in which the oxidation of glutamic acid results in a fluorescent product (λex =540/λem = 590 nm) proportional to the glutamate oxidase activity present. One unit of glutamate oxidase activity is defined as the amount of enzyme that catalyzes the conversion of L-glutamic acid to 1.0 μmole a-ketoglutaric acid per minute at pH 7.4 at room temperature.

Application

Suitable for measuring glutamate oxidase activity in a variety of samples such as solutions and cell extracts.
