    摘要: Affinity bound collagen matrices for the delivery of biologically active agents, and methods for preparing such matrices, are disclosed. A preferred method for preparing the matrices of the invention comprises mixing a binding ligand and an active agent together, allowing the resulting binding ligand-active agent mixture to form an affinity bound complex, then combining the resulting affinity bound complex with collagen to form a matrix. Particular affinity bound matrices comprising collagen, heparin, and an active agent are also disclosed, as well as methods for using the matrices of the invention for delivery of biologically active agents.

    摘要: The present invention discloses collagen cross-linked in a micro to non-fibrillar form and at a high concentration. The cross-linked collagen gel has improved volume stability or persistence than collagen cross-linked at a neutral pH. Also disclosed are methods for preparing the inventive cross-linked collagen and using such for augmenting soft tissues in mammals.
