Lowry protein assay

The Lowry protein assay is a laboratory method used to measure the amount of protein in a sample. It works by reacting the proteins with specific chemicals, producing a color change that can be measured with a spectrophotometer. The intensity of the color correlates with the protein concentration—more protein results in a darker color. This assay is widely used because of its sensitivity and reliability for quantifying proteins in various biological samples, such as cell extracts or food products, helping researchers determine protein content accurately.
