Field correlation function g(τ) of light scattered by aggrecan (0.6% w/w), aggrecan-HA (0.6% w/w) and HA (1% w/w) solutions. The aggrecan and aggrecan-HA solutions contain 100 mM NaCl, while the HA solution in addition contains 100 mM CaCl2. Inset: variation of fast relaxation rate Γf with q2 for the HA solution.
