Activity of Neogen's TMB Substrates

Custom TMB Substrate is a one bottle stabilized chromogenic substrate for use with horseradish peroxidase immunoassays. It contains both 3,3’,5,5’ tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) in a one bottle format with long term stability and lower sensitivity. Custom TMB Substrate develops a deep blue color in the presence of peroxidase labeled conjugate. It is not applicable for use with assays requiring a precipitating substrate. This formulation does NOT contain DMF or DMSO.

Sensitivity: Custom TMB Substrate is ideal for assays requiring a slower kinetic reaction. This formulation provides an activity level 20-30% lower than Neogen’s Enhanced K-Blue formulation.

Appearance: Clear to faint blue solution

Stability and Storage: Custom TMB Substrate is stable for a minimum of 36 months when stored at 4°C.

Custom Packaging Service: Neogen can package Custom TMB 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 Corporation representative.
