WebBiuret reagent is used for measuring total protein concentration. It comprises of copper II (cupric ion) alkaline solution, which interacts with the peptide bond to form a blue adduct which is measured at 540nm. Biuret method is less sensitive when compared to other protein estimation methods like Lowry and Folin-Ciocalteu techniques.
