规格：100 / 200 assays per kit

Megazyme’s catalase assay kit provides a simple colourimetric method for the measurement of catalase activity. The method is delivered in a fast and reliable format and may be used to detect catalase activity in various samples, including food, biological and bacterial samples. The calculation method included allows for significant variation in the concentration of the H₂O₂substrate solution that is employed in the assay which translates into a reduction in the ‘hands on’ time required by the analyst in comparison to other commercial kits.

Colourimetric method for the determination ofcatalase activity.

Principle: (catalase) (1) 2H₂O₂→H₂O+O₂ (peroxidase) (2)2H₂O₂+ DHBS+ AAP→quinoneimine+ 4H₂O (purple colour) Note: DHBS=3,5-Dichloro-2-hydroxybenzenesulfonic acid AAP =4-aminoantipyrene

Kit size: 100 / 200 assaysMethod: Spectrophotometric at 520 nmTotal assay time: 20 minDetection limit: 0.5 U/mLApplication examples: Various food, biological and bacterial samples Method recognition: Novel method
