Coomassie Brilliant Blue

Coomassie Brilliant Blue is a dye commonly used in laboratories to detect and quantify proteins. When added to a sample, the dye binds specifically to proteins, causing a color change from brown to blue. The intensity of the blue color correlates with the amount of protein present, allowing scientists to measure protein concentration visually or with instruments. This method, known as the Bradford assay, is quick, sensitive, and widely used because it is reliable and easy to perform. Overall, Coomassie Brilliant Blue is an essential tool for studying protein levels in biological samples.
