Effect of PRG4 concentration on cartilage boundary lubricating ability. μstatic,Neq for PRG4 low dose (Test 1A, a), and PRG4 high dose (Test 1B, b). <μkinetic,Neq > at Tps = 1.2 s (c) for PRG4 high and low dose response + constant [HA] = 3.3 mg/mL (Tests 1A, 1B). Average < μkinetic,Neq > in PBS and SF shown in grey for reference. * = significantly higher than SF (p < 0.05)
