Top Down Milk Protein Identification and Relative Quantification by Q Exactive Mass Spectrometer
DescriptionWhey proteins, most notably alpha-lactalbumin and beta-lactoglobulin, are currently being investigated for their potential positive health benefits. Whey proteins are a substantial percentage of human milk (~60%) while such proteins are less abundant in cow milk (~20%). We describe a method for the identification of the various forms of caseins and whey proteins as a first step and then intact protein-based method for determination of the whey vs. casein protein ratio.
