the hspg had a lower bouyant density ( less than 1.45 g/ml ) than the dermatan sulfate/chondroitin sulfate proteoglycan and was heterogeneous , as was evident in the fact that hspg attained equilibrium over a wide range of cscl densities and also showed nonuniform interaction with octyl-sepharose .
