The Bradford protein assay (also known as the Coomassie protein assay) was developed by Marion M. Bradford in 1976. [1] It is a quick and accurate [ 2 ] spectroscopic analytical procedure used to measure the concentration of protein in a solution.
This is the basis of the Bradford assay, which quantifies protein by Coomassie brilliant blue dye binding. The binding of the dye to a protein causes a shift in the absorbance maximum of the dye from 465 to 595 nm. The increase of absorption at 595 nm is monitored to determine protein concentration. [9]
Marion Mckinley Bradford (October 28, 1946 - May 3, 2021) was an American scientist [1] who developed and patented the Bradford protein assay, [2] a method to quickly quantify the amount of protein in a sample. [3] [4] His paper describing the method is among the most cited scholarly articles of all time. [5] [6] [7]
An alternative method for label free protein quantification in clear liquid is cuvette-based SPR technique, that simultaneously measures the refractive index ranging 1.0 to 1.6 nD and concentration of the protein ranging from 0.5 μL to 2 mL in volume. This system consists of the calibrated optical filter with very high angular resolution and ...

Protein purification is a critical process in molecular biology and biochemistry, aimed at isolating a specific protein from a complex mixture, such as cell lysates or tissue extracts. [9] The goal is to obtain the protein in a pure form that retains its biological activity for further study, including functional assays, structural analysis, or ...
