Millon's test a test for the presence of protein in a mixture, involving the use of Millon's reagent which contains mercuric nitrate and nitrite. On heating a proteinaceous solution with a few drops of Millon's reagent (using a fume cupboard) a purplish precipitate is formed. The test is less commonly used today because of the danger associated with handling mercuric salts, the BIURET REACTION being employed instead.
