Summary
A low mol.wt, dialyzable glycosaminoglycan was isolated from human aorta and was found to be homogeneous on 2 dimensional electrophoresis. As judged by its electrophoretic mobilities and its hydrolysis by chondroitin sulfatase ABC, it was concluded that this hitherto unknown glycosaminoglycan is an oversulfated chondroitin sulfate.

The weight of this fraction was too small for analysis.

In control experiments carried out to assess the effect of papain and of incubation at pH 1–2 on high mol.wt GAGs, it could be established that to dialyzable mucopolysaccharides were formed.
