Enhanced K-Blue® is a one bottle stabilized chromogenic substrate for use with horseradish peroxidase (HRP) immunoassays. It contains both 3,3’,5,5’ tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2). Enhanced K-Blue develops a deep blue color in the presence of peroxidase labelled conjugate. Enhanced K-Blue has been optimized for use with microwell applications, especially ELISA. This substrate is not applicable for use with assays requiring a precipitating substrate.
