High Sensitivity and Stable Color

For real-time, quantitative enzyme conjugate assays of immunology and glycobiology

A single step reagent for sub-picogram quantification of horseradish peroxidase in enzyme-linked immunosorbent assays and lectin-conjugate assays of glycobiology. Sensitive Blue™ reagent is deigned to stabilize the blue chromophore, single oxidation product of 3,3’,5,5’-tetramethyl-benzidine (TMB). This eliminates the necessity of assay development by the addition of a strong acid, stop reagent, allowing quantitative data to be obtained in real-time using a visible wavelength spectrophotometer or digital camera.
