Enzyme assays are used to measure the level of enzymatic activity in a sample and are vital for the study of enzyme kinetics and inhibition. Based on the level of enzyme inhibition, the assays identify different bacteria strains through easy-to-read indicators such as changes in colour, turbidity, sedimentation, precipitation, and colourful formations. The presence or absence of enzyme activity is a taxonomic property of microorganisms and can be used for differentiation or identification.

Oxidase sticks for microbiology
Supplier: PanReac AppliChem
Plastic sticks used for the easy and rapid detection of the cytochrome oxidase enzyme in microbiological diagnosis. Oxidase sticks have a much higher stability compared to the traditional laboratory test, because the tetramethyl-p-phenylenediamine reagent is attached to the pad.
