K-Blue® Advanced is a one-bottle stabilised chromogenic substrate for use with horseradish peroxidase (HRP) immunoassays. K-Blue Advanced offers superior sensitivity, long-term stability and is 100% REACH compliant so no additional hazardous labelling is required for transporting or use. K-Blue Advanced develops a deep blue colour in the presence of peroxidase labelled conjugate and has been optimised for microwell assay applications, including ELISA. K-Blue Advanced is not applicable for use with assays requiring a precipitating substrate. Sensitivity: K-Blue Advanced is a highly sensitive substrate. The formula offers comparable performance to Enhanced K-Blue and can offer higher sensitivity in certain assays. This formula features a linear response across a wide range of HRP concentrations and offers the most rapid turn-over rate of Neogen’s TMB substrates. K-Blue Advanced features high signal-to-noise and offers very low background. Stability and Storage: K-Blue Advanced is stable for a minimum of 24-months when stored at 2-8°C. Appearance: Clear to faint blue solution.
