What is the purpose substrate TMB
The enzyme horseradish peroxidase (HRP), found in the roots of horseradish, is used extensively in biochemistry applications primarily for its ability to amplify a weak signal and increase detectability of a target molecule.It is a metalloenzyme with many isoforms, of which the most studied type is C.orseradish peroxidase is a 44,173.9-dalton glycoprotein with 6 lysine residues which can be conjugated to a labeled molecule. TMB (3,3',5,5' -tetramethybezidine) is commonly used in HRP-based ELISA (emzyme-linked immunosorbent assay). This TMB reagent is formulated as all-in-one, ready to use HRP substrate.The reagent contains all essential components (TMB, substate buffer and H 2 O 2) in one solution for HRP enzyme reaction.When HRP enzyme reaction occurs, the substrate reagent produces a blue color reaction product.MB (3,3',5,5' -tetramethybezidine) is commonly used in HRP-based ELISA (emzyme-linked immunosorbent assay). This TMB reagent is formulated as all-in-one, ready to use HRP substrate. When the substrate is a TMB substrate where the reaction product between TMB, peroxide and HRP is measured at around 450 nm (yellow), it is preferred that the substrate (dye) has a visible colour in the range of 500-600 nm, i.e. in the range clear of the blue and the yellow colours of TMB.or the detection of the enzyme activity is needed a specific enzyme substrate for the actual enzyme. Various enzyme substrates such as ortho-phenylenediamine (OPD), 2,2′-azino-bis-(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) and 3,3′,5,5′-tetramethylbenzidine (TMB) are commonly used. In the presence of horseradish peroxidase (HRP) enzyme conjugates, TMB and peroxide react to produce a blue byproduct having maximum absorbance at 605nm. The color intensity is proportional to the amount of HRP activity, which in turn is related to the levels of target analyte in an optimized ELISA procedure.tore at room temperature or 2-8°C. • Application: ELISA: Following TMB incubation, add an amount of stop solution equal to the amount of TMB substrate added to each well of the ELISA plate (typically 50 - 100 mL per well). Use at full strength. Horseradish peroxidase is a 44,173.9-dalton glycoprotein with 6 lysine residues which can be conjugated to a labeled molecule.It produces a coloured, fluorimetric, or luminescent derivative of the labeled molecule when incubated with a proper substrate, allowing it to be detected and quantified.orseradish peroxidase is a 44,173.9-dalton glycoprotein with 6 lysine residues which can be conjugated to a labeled molecule. Horseradish peroxidase catalyses the oxidation of luminol to 3-aminophthalate via several intermediates. The reaction is accompanied by emission of low-intensity light at 428 nm.orseradish peroxidase is a 44,173.9-dalton glycoprotein with 6 lysine residues which can be conjugated to a labeled molecule. Stop Solution is 0.16M sulfuric acid for use with the ELISA substrate 3,3’,5,5’ - tetramethylbenzidine (TMB).tore at room temperature or 2-8°C. • Application: ELISA: Following TMB incubation, add an amount of stop solution equal to the amount of TMB substrate added to each well of the ELISA plate (typically 50 - 100 mL per well). Use at full strength. We offer one colorimetric (also called chromogenic) substrate for ELISA development with alkaline phosphatase (AP) and three substrates for horseradish peroxidase enzyme (HRP): 1  PNPP (p-Nitrophenyl Phosphate, Disodium Salt) is a widely used substrate for detecting alkaline phosphatase in ELISA applications.LISA substrates require a variety of procedures for preparing the substrate working solution and detecting the signal. Some substrates are ready to use, while others require additional materials to be supplied. In addition, each substrate has unique requirements for optimization.
