Rapid, modified oxidase test for oxidase-variable bacterial isolates

optimization of bacterial urate oxidase enzyme activity

NADPH Oxidase NOX2 Mediates Rapid

Methods for storing oxidase test reagents.

Oxidase test reagents are notoriously unstable, but they can be held ready for use if frozen or if reagent-impregnated filter paper is kept dry.

The phagocyte NADPH oxidase and bacterial infections

Neutrophils play a crucial role in host defense against microbial infections. During phagocytosis of invading bacteria or fungi, the phagocyte NADPH oxidase produces superoxide. The importance of the oxidase is exemplified by the genetic disorder known as chronic granulomatous disease (CGD). The neutrophils of CGD patients cannot produce superoxide, with the result that affected infants and chi...

Direct Electrochemistry of Polyphenol Oxidase

The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...
