Molecular weight and polydispersity of hyaluronic acid in ethylene oxide terminally sterilized GAGF (taken from a CMP sample) (‘Post-EO’), and GAGF prior to ethylene oxide terminal sterilization (‘Pre-EO’).

GAGF Condition	Weight average molecular weight Mw (kDa)	Number average molecular weight Mn (kDa)	Polydispersity Mw/Mn	Intrinsic viscosity (η) (mL/g)
Pre-EO	1070 ± 7	788 ± 1	1.4 ± 0.1	12.06 ± 0.33
Post-EO	656 ± 1	411 ± 2	1.6 ± 0.1	7.71 ± 0.07

Values represent average and standard deviations from duplicate samples; EO: ethylene oxide; Mn: average molecular weight; Mw: average polydispersity
