extraction of the skin of newborn rat yielded two populations of galactosaminoglycan-containing proteoglycan : a mr = 111,000-200,000 dermatan sulfate proteoglycan ( ds-pg ) with a mr congruent to 55,000 core glycoprotein and a mr congruent to 10 ( 6 ) chondroitin sulfate proteoglycan ( cs-pgs ) composed of two subpopulations with different size core-glycoproteins ( mr congruent to 480,000 and 520,000 ) .
