Lowry assay
The Lowry assay is a scientific method used to measure the amount of protein in a sample. It works by mixing the sample with specific chemicals that react with proteins, creating a color change. The intensity of this color correlates with the protein concentration and can be measured using a spectrophotometer — a device that detects light absorption. The more protein present, the deeper or more intense the color. This assay is widely used in laboratories to determine protein levels in biological research and medical tests accurately.
