TMB Membrane Substrate is a ready to use solution. It contains 3,3’,5,5’-tetramethyl-benzidine in a mildly acidic buffer in a one bottle format. TMB Membrane Substrate develops an insoluble, permanent dark blue reaction in the presence of peroxidase. The substrate is intended for western blot, dot blots and line assays and offers comparable performance and sensitivity to some chemiluminescent substrates. This substrate is not recommended for microwell or immunohistochemical applications.

Sensitivity: TMB Membrane Substrate offers extremely sensitive horseradish peroxidase (HRP) detection in the low picogram range. This formula offers a high signal-to-noise ratio, making it resistant to fading.

Stability and Storage: TMB Membrane Substrate is stable for 2 years, from the date manufacture, when stored at room temperature (15° to 25°C) or 48 months when stored at 2° to 8°C.

Custom Packaging Service: Neogen can package TMB Membrane Substrate in custom bottle sizes and volume fills to meet your specific packaging requirements. This service is a time and cost saving feature for any test kit manufacturer. For details on this service, please contact a Neogen representative.
