Specifications

This Catalase BioAssay™ Kit detects high pico-unit of catalase in samples using either Absorbance- (570nm) or Fluorescence- (Ex/Em 535/587nm) based methods. Samples from mammalian species can be from cell and tissue culture supernatants, urine, plasma and serum, as well as many other biological fluids, growth medium, food, etc.
Catalog #	C2090-10
	Catalase (EC 1.11.1.6) is a ubiquitous antioxidant enzyme that is present in nearly all living organisms. It functions to catalyze the decomposition of hydrogen peroxide (H202) to water and oxygen. The Catalase BioAssay™ Kit provides a highly sensitive, simple, direct and HTS-ready assay for measuring Catalase activity in biological samples. In the assay, catalase first reacts with H2O2 to produce water and oxygen, the unconverted H2O2 reacts with Oxidation/Reduction probe to produce a product, which can be measured at 570nm (Colorimetric method) or at Ex/Em=535/587nm (fluorometric method). Catalase activity is inversely proportional to the signal. The kit detects high pico-units of catalase in samples.
