100% Solvent Free Activity of Neogen's TMB Substrates

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 labeled conjugate and is ideal for end users working under strict regulatory requirements. 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 Corporation representative.
