the labeled proteoglycans extracted from control kidneys eluted as a single peak with kav = 0.25 ( mr = approximately 130,000 ) , and approximately 95 % of the radioactivity was associated with heparan sulfate proteoglycan ( hs-pg ) , the remainder with chondroitin ( or dermatan ) sulfate proteoglycan ( cs-pg ) .
