Reading the Biuret Test
Add a few drops of the reagent to the sample solution and shake; no heating is needed. In alkaline solution, copper(II) ions bind to the peptide bonds that link the amino acids in a protein and form a violet complex. Egg white and milk give a clear purple, while a solution that stays blue has no protein. Free amino acids do not give the colour, as they have no peptide bonds.
Keep the bottle capped in a cool place.
