Functional aspects of blood plasma proteins.

Abstract
Summary: Porcine plasma proteins were fractionated by ion‐exchange chromatography on DEAE‐Sephadex using continuous ionic gradient elution. The separation was scaled up to produce gram quantities of three fractions, by stepwise elution. Subsequent diafiltration resulted in fractions of high protein content. The whole plasma, serum and the resultant fractions, and commercially available dried plasma, were characterized by polyacrylamide gel electrophoresis.
