Web12 apr. 2024 · Hyaluronic acid (HA) was modified with methacrylic anhydride (MA) as previously described in an established protocol . Equimolar concentrations of HA (1000 kDa) and MA were reacted to obtain a 50% degree of substitution (DS) HA-MA. Generated HA-MA was purified via dialysis and freeze-dried to produce a white, fibrous product. WebNational Center for Biotechnology Information
