Reagent for Protein Determination

The determination of protein concentration is essential for biochemical research. Pyrogallol Red (Ready-to-use solution) (1) is supplied as a ready-to-use solution for quantitative protein determination. 1 reacts with molybdate to afford the pyrogallol red-molybdate complex with maximum absorption at 480 nm. Subsequently the complex is bound to proteins thereby shifting the maximum absorption to 600 nm. Thus, 1 can be applied to determine the amounts of proteins in test samples because absorbance of the protein-binding complex at 600 nm increases linearly in proportion to the amount of proteins. This solution stains cuvettes negligibly, and the cuvettes can be washed with water alone.
