heparitinase treatment of the heparan sulfate proteoglycan fraction ( containing 86 % heparan sulfate and 10 % chondroitin sulfate ) that was eluted from the lipoprotein lipase affinity column with 1 m nacl led to the appearance of a major protein core with a molecular size of 55,000 daltons , as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis .
