Distribution of Glycoproteins in Normal Human Plasma.

Abstract
Five-ml samples of normal human plasma were separated by a low temperature-low salt-ethanol procedure into 4 primary fractions, I+IH, II, IV+V, and VI. The concentrations of protein-bound carbohydrate (hexose) and protein in whole plasma and the 4 primary fractions, and the protein-bound carbohydrate content of seromucoid were determined. Fraction IV+V contained the greatest amount of protein-bound carbohydrate and protein. The percentage of protein-bound carbohydrate in relation to protein was highest in Fraction VI.
