31817064-3	2019	Freezing of the CHI-HA-GA and PVA-Hep-GA mixture led to the formation of a non-stoichiometric PEC between oppositely charged groups of CHI and Hep, which caused further efficient immobilization of bone morphogenic protein 2 (BMP-2) possible due to electrostatic interactions.	Polyvinyl Alcohol	30-33	bone morphogenetic protein 2	Rattus norvegicus	197-223
