TMB HRP Membrane Substrate One Component 'Ready to Use'

TMB HRP Membrane Substrate (3,3?,5,5? tetramethylbenzidine) is a precipitating substrate used with the enzyme horseradish peroxidase (HRP) designed for various membrane immunoassays but not recommended for microwell or immunohistochemical applications. Initially, the substrate should be slightly yellow to pink in color and is formulated in a mildly acidic buffer. TMB HRP Membrane Substrate turns a deep blue color when reacted with horseradish peroxidase labeled conjugates. Leinco Technologies? TMB HRP Membrane Substrate is a highly sensitive, high performance formulation that produces a high signal to noise ratio with low membrane background. The outstanding shelf life of at least thirty months for the TMB Membrane Substrate makes this reagent ideal for long term use of the same manufacturing lot.
