Leírás

Általános leírás

Insoluble TMB substrate supplied as a single component system. TMB is the most sensitive chromogenic substrate for detection of horseradish peroxidase (HRP)-labeled probes. In the presence of HRP and hydrogen peroxide (H₂O₂), TMB is oxidized first to a blue, cation free radical; upon further reaction with HRP/H₂O₂, or addition of acid, the radical is converted to a yellow diimine terminal oxidation product. TMB is used routinely in ELISA procedures, whereby its soluble oxidation products are measured spectrophotometrically. For TMB to be worthwhile as a blotting reagent, enhancers such as dextran sulfate or other sugar polymers are usually added.This TMB reagent is a safe, single component system that has been developed for use in blotting procedures by a proprietary methodology that eliminates the use of sugar polymers. The reagent produces a stable, insoluble aquamarine precipitate at the reaction site with little or no background. It can significantly increase the detection limits of assays on a variety of membranes. Ideal for many immunoblotting procedures and can significantly increase detection limits of assays on a variety of membranes

Peroxidase substrate that produces a stable, insoluble, aquamarine blue precipitate at reaction site with little or no background.
