DESCRIPTION
General description
Bactident™ Oxidase test strips are designed to detect cytochrome oxidase positive microorganisms in a test sample or grown culture. Cytochrome oxidase is an enzyme found in specific microbes which will catalyze the substrate cytochrome c indicated by a color change of blue to blue violet. This reaction can be used to classify and identify the bacteria. In the presence of molecular oxygen, the cytochrome oxidase/cytochrome c system can reduce all the available organic substances in the environment e.g. NaDi (1-naphthol dimethylparaphenylene diamine) reagent with the formation of condensation molecule indophenol blue.
Application
Bactident™ Oxidase test strips are used to detect cultured microorganisms which can catalyze cytochrome c substrate through a color change reaction.
