摘要

The present disclosure is directed to a two-part cytocompatible system for preparing a cytocompatible composition for use in repairing tissue of a subject. The system comprises an admixture of a first-part liquid solution of a polysaccharide, such as chitosan and a second-part liquid solution of a salt, such as glycerol phosphate. When the chitosan and glycerol phosphate solutions are combined, a cytocompatible composition is produced which is free of polymer precipitation at room temperature. The composition also promotes non-covalent complex formation between chitosan and therapeutic anionic proteins with a pl 6 78.
