Studies on fast-moving albumins in human serum

Abstract

Normal human serum can be separated by continuous paper electrophoresis or by elution from agar gel columns to yield tractions with electrophoretic mobilities greater than that of crystalline human serum albumin, but in no case was evidence of a fast-moving protein found that had an immunological specificity different from that of crystalline human serum albumin. The prealbumin found by the German workers does not appear to be an albumin, but may be a fast-moving globulin such as a glycoprotein.
