Solution to detect albumin
WebHand-warm the precipitate until it becomes liquid (you can do this in a water bath set at 40). The easiest test to do to see the positive result is to test egg white or milk. Add some of the egg white to the Biurets solution in the test tube and mix thoroughly while still hand warming. The blue colour will change to violet if protein is present. WebScience Chemistry Bovine serum albumin (BSA) is a biochemically useful protein. A 0.360 g sample of bovine serum albumin is dissolved in water to make 0.158 L of solution, and the osmotic pressure of the solution at 25 °C is found to be 0.851 mbar. Calculate the molecular mass of bovine serum albumin. molecular mass: g/mol.

WebNov 15, 2015 · 1 Answer. In my experience, when protein denatures, it typically aggregates and precipitates from solution. I would expect a denatured protein to create a cloudy solution, or actual precipitates in the form of little globs or fine wisps. A solution where protein is correctly formed and solubilized in the solution should be clear.
