title: A rapid method of isolation and fractionation of proteoglycans using a vertical tube rotor for isopycnic centrifugation.
abstract: A comparison was made between a vertical tube rotor and a fixed angle rotor for isopycnic centrifugation of proteoglycans. In the vertical tube rotor, isopycnic gradient was achieved much faster than in the conventional fixed angle rotor. The use of a vertical tube rotor for isopycnic centrifugation shortens the time considerably for the isolation of proteoglycans from various tissues.
