Abstract
IN a previous investigation1, I subjected the non-ultra-filterable substances from normal urine to preparative zone electrophoresis at pH 8.6 and 4.5 and described a urinary glycoprotein fraction which had a high mobility towards the anode at both pH's. The mobility at pH 8.6 was similar to that of albumin, and the material was characterized by a relatively high sialic acid content and a relatively small pep tide content1. It is the purpose of the present communication to report on the isolation and partial chemical characterization of this sialic acid-rich glycoprotein fraction.
