K-Blue® Aqueous Substrate (TMB)

K-Blue^® Aqueous is a revolutionary 100% solvent-free, non-volatile TMB substrate. It contains 3,3’,5,5’ tetramethylbenzidine (TMB) and hydrogen peroxide (H₂O₂) in a one-bottle format with long-term stability and high activity. K-Blue Aqueous develops a deep blue color in the presence of peroxidase labelled conjugate and is ideal for end users working under strict regulatory requirements. K-Blue Aqueous has been optimized for use with microwell applications, especially ELISA This substrate is not applicable for use with assays requiring a precipitating substrate.

Sensitivity: This highly sensitive TMB substrate offers kinetic reactions similar to Neogen’s Enhanced K-Blue Substrate and offers low background development.

Stability and Storage: K-Blue Aqueous is stable for 36 months when stored at 4°C.

Appearance: Clear to light yellow-green solution

Custom Packaging Service: Neogen can package K-Blue Aqueous 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.
