A protein standard, bovine serum albumin, is eluted from this column with linear response to a concentration of 1 g/L. Protein is separated from other UV absorbing components of must and wine and estimated at 280 nm on a Waters Protein Separation System with a 0.1-M ammonium acetate mobile phase containing 10% glycerol. The method is now used routinely for estimation of protein in must and wine.
