Polymer p(SS-co-PEGMA) stabilizes FGF2 as a conjugate and pVS facilitates FGF2-receptor binding when added as an excipient. When combined into a block copolymer, p(SS-co-PEGMA)-b-VS, the new conjugate both stabilizes FGF2 and increases protein activity. Protein structure modified from PDB 1CVS using PyMOL software.
