Thermo Fisher, A22188, Amplex™ Red Hydrogen Peroxide/Peroxidase Assay Kit

Quantity: 500 Assays
Unit Size: Each
Assay uses AmplexRed reagent (10-acetyl-3,7-dihydroxyphenoxazine) to detect hydrogen peroxide (H_2O_2) or peroxidase activity in vitro. AmplexRed reagent, in combination with horseradish peroxidase (HRP), can detect H_2O_2 released from biological samples, including cells, or generated in enzyme-coupled reactions. AmplexRed reagent can also be used as an ultrasensitive assay for peroxidase activity when H_2O_2 is in excess. In the presence of peroxidase, AmplexRed reagent reacts with H_2O_2 in a 1:1 stoichiometry to produce the red-fluorescent oxidation product, resorufin. Resorufin has excitation and emission maxima of approximately 571 nm and 585 nm, respectively, and because the extinction coefficient is high (58,000 ± 5000cm–^1M–^1), the assay can be performed fluorometrically or spectrophotometrically. This reaction has been used to detect as little as 10 picomoles of H_2O_2 in a 100μL volume or 1 x 10–5U/mL of HRP.
• Can detect as little as 10 picomoles of hydrogen peroxide or 10μU/mL of horseradish peroxidase activity in a 100μL assay volume
