Figure 1. — Characterizations of the investigated gels. Size exclusion chromatography analysis of sHA released from the gels after extraction to assess (A) the mean Mw of the released sHA fragments, (B) the percentage of released sHA per syringe, and (C) the percentage of released low Mw sHA per syringe in the distribution ranges of [0–250 kDa], [0–100 kDa], and [0–30 kDa]. (D) 1H NMR analysis of the gels to assess the MoD of the enzymatically digested gels. sHA, soluble hyaluronic acid; MoD, degree of modification.
