The Precision Red Advanced Protein Assay Reagent is designed to extend the linear range of protein measurement, a limiting factor in other protein assays. The reagent combines the useful properties of low protein to protein variance and a broad linear response to many types of purified protein. A simple one step procedure results in a red to purple/blue color change characterized by an increase in absorbance at 580 to 620 nm.
1) To determine protein concentration in a variety of common buffers. 2) To determine protein concentration in biological fluids (e.g. serum or saliva). 3) To determine protein concentration in tissue culture media. 4) To follow protein purification steps in combination with activity assays.
1) 1 x 500 ml Advanced Protein Assay Reagent (1X concentrate). Store at room temperature for up to 6 months.
