Open publisher page 3 citations

Abstract

Fractionation of bovine whey concentrate was performed by gel filtration on Sephadex G-75 both on a laboratory scale and on a large scale. By a recycling procedure and improved separation was obtained and the whey proteins were resolved into four fractions in the weight ratio 3:12:1:4. The fractions were analysed by polyacrylamide gel (PAG) electrophoresis and the apparent molecular weights were determined by thin layer gel chromatography (TLG) and by sodium dodecylsulfate (SDS) gel electrophoresis.
