3,3',5,5'-tetrametylobenzydyna membrane peroxidase substrate Plus, liquid, Biotechnology Grade 1 component
3,3',5,5'-tetrametylobenzydyna

Ready to use sensitive substrate for the detection of horseradish peroxidase (HRP) activity suitable for ELISA and solution assays. Offers faster signal, enhanced sensitivity and the lowest possible background.


  • Ready to use solution


Reaction of the substrate with HRP generates a free-radical cation that exhibits blue colour with an absorption maximum at 653 nm. Acidification of the reaction by addition of sulfuric acid yields a yellow-coloured diimine terminal oxidation product, which absorbs light at 450 nm.


TMB Plus liquid component substrate is optimised with TMB and hydrogen peroxide concentrations that allow a linear response to typical HRP concentrations utilised in immunologic assays.


Informacje do zamówienia: Contains 2,08 mmol/l TMB, hydrogen peroxide, citric acid buffer pH 3,3 and additional proprietary, non toxic stabilisers.


Sposób pakowania: Packed in plastic bottle.
