An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, and molecular biology for qualitatively assessing or quantitatively measuring the presence or functional activity of the analyte, or the entity being targeted by the assay. Generally, assays involve biological materials or phenomena which tend to be intrinsically more complex in composition or in behavior than what can be handled by traditional chemical analysis and titration.

HRP substrate, 1-Step™ Ultra TMB-ELISA
Supplier: Thermo Fisher Scientific
The 1-Step™ Ultra TMB-ELISA contains soluble TMB (3,3´,5,5´-tetramentylbenzidine) that is ideal for sensitive ELISA-based applications. TMB is a chromogenic substrate for horseradish peroxidase. Once oxidised by the enzyme, this substrate yields a blue product that absorbs at 370 nm and 652 nm. Adding sulfuric or phosphoric acid to stop the reaction changes the product to yellow that absorbs at 450 nm and provides greater sensitivity than the blue product. The 1-Step Ultra TMB-ELISA is supplied ready to use with no mixing required.

HRP substrate, 1-Step™ Turbo TMB-ELISA
Supplier: Thermo Fisher Scientific
TMB (3,3´,5,5´ tetramethylbenzidine) is a substrate for horseradish peroxidase (HRP). The 1-Step™ Turbo TMB-ELISA is a complete solution that contains TMB and a stabilised hydrogen peroxide. TMB has an absorption maximum at 285 nm before oxidation. After oxidation, the maxima are 370 and 652 nm. The blue solution can be measured at 652 nm. However, upon addition of the stop solution (ie. acid) a yellow solution results that can be measured at 450 nm and has a higher sensitivity than the measurement of the blue solution.
