One common chemical used to detect proteins is Biuret reagent, which contains copper sulfate. When proteins are present, the copper ions in the reagent react with the peptide bonds, resulting in a color change to violet. This color change can be measured spectrophotometrically to determine protein concentration. Another popular method involves using Coomassie Brilliant Blue dye, which binds to proteins and also produces a color change that can be quantified.
