Polymer Distribution in Human Serum Albumin Powders Prepared by Lyophilization or Acetone Drying

Abstract

Various lots of human serum albumin, prepared by the Cohn alcohol procedure, were assayed for polymer distribution after lyophilization or acetone drying of the albumin paste. Sodium dodecyl sulfate polyacrylamide gel electrophoresis revealed that powders obtained by acetone drying of the pastes contained significantly higher amounts of monomeric albumin.
