Biuret Reagent - Working Solution

What is Biuret Reagent? It is a chemical reagent used to test for the presence of proteins. It contains copper(II) sulphate dissolved in an alkaline solution, typically sodium hydroxide (NaOH). When proteins are present, the copper ions in the solution bind to the peptide bonds within the protein, resulting in a colour change from blue to purple. This colour change is the basis of the Biuret test, which is commonly used in laboratory settings to detect and quantify proteins in various samples, such as blood, urine, or biological tissues.
