Hyaluronidase treatment of the culture supernatant of HFLS-RA cells. Culture supernatant fractions of 0.01% HA-stimulated (a) and 0.01% SI-613-stimulated (b) cells were incubated in the absence or presence of hyaluronidase, then analyzed by size exclusion HPLC using an OH pak SB-805 HQ column. The data represent results from a single HPLC run with a single well
