WebBackground: TMB (3,3’, 5,5”-tetramethylbenzidine) is used as a substrate to generate detectable signal in ELISA. The reaction between the TMB substrate and a peroxidase, typically horseradish peroxidase (HRP), produces a measur-able color change that correlates with analyte level. TMB is intended for use in combination with CST’s FastScan™ quicken windows vs quicken mac https://btrlawncare.com
