{"product_id":"catalase-assay-tbs2006","title":"Catalase Assay","description":"\u003cp\u003eCatalase (EC 1.11.1.6) is an ubiquitous antioxidant which catalyzes the conversion of hydrogen peroxide (H\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e) into water (H\u003csub\u003e2\u003c\/sub\u003eO) and oxygen (O\u003csub\u003e2\u003c\/sub\u003e). H\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e is an oxidative stress inducer that can cause damage cells at relatively low concentrations. H\u003csub\u003e2\u003c\/sub\u003eO\u003csub\u003e2\u003c\/sub\u003e is also precursor to certain oxidant radical species (e.g. hydroxyl radical). Catalase plays a crucial role to prevent oxidative damage to the cells.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eTribioscience catalase Assay Kit provides a rapid, simple, reproducible, and sensitive tool for catalase activity determination in plasma, serum, urine, and other samples. The catalase activity assay uses enzyme reactions to produce color and fluorescence with the probe. The color intensity of the reaction at 570 nm or fluorescence intensity at λex\/em = 530\/590 nm is directly proportional to catalase concentration in the sample. The fluorometric assay is more sensitive than colorimetric assay.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003eAPPLICATIONS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDirect Assays: \u003c\/strong\u003eCatalase enzyme activity in serum, plasma, urine, and other bio-samples.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 18px\"\u003e\u003cstrong\u003eKEY FEATURES\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFlexible: \u003c\/strong\u003eSuitable for colorimetric and fluorometric methods.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAccurate:\u003c\/strong\u003e Use 25 µL samples, detection ranges are 1.95-31.25 U\/mL in 96-well plate the assay.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSimple and high-throughput\u003c\/strong\u003e: Two-steps procedure: just load-incubate-adding-incubate-read.
