Patent number: 8637455Abstract: The presently disclosed subject matter relates to peptides having binding affinity for glycopeptide antibiotics and methods and compositions for delivering glycopeptide antibiotic to the surface of medical devices. The peptide compositions can comprise a peptide having binding affinity for a surface material of a medical device that is coupled to the peptide having binding affinity for glycopeptide antibiotic. Also provided are methods of applying the peptide compositions to a medical device by contacting the peptide compositions with a surface of the medical device. In addition, kits are provided comprising the peptide compositions.Type: GrantFiled: October 17, 2008Date of Patent: January 28, 2014Assignees: Affinergy, LLC, DePuy Synthes Products, LLCInventors: Martyn K. Darby, Isaac G. Sanford, R. Edward Benson, Hanne Gron, Paul T. Hamilton, Shrikumar A. Nair, Doug Buechter, Elliott Gruskin

Patent number: 7972615Abstract: The presently disclosed subject matter provides compositions comprising a first substrate-binding domain (a peptide or a polymer) having binding affinity for a tissue or a medical device, a second substrate-binding domain having binding affinity for a target molecule, and the target molecule. In some embodiments, the first and second substrate-binding domains are covalently linked. The first and second substrate-binding domains are covalently coupled to at least one hydrophobic interaction tag, negatively charged interaction tag, or positively charged interaction tag. When the substrate-binding domains are combined and coated onto the tissue or medical device, the hydrophobic interaction tags interact with each other and the charged interaction tags interact with the oppositely charged interaction tags or the oppositely charged substrate binding polymers, to form a macromolecular network of non-covalently coupled substrate-binding domains to load the target molecule onto the tissue or medical device.Type: GrantFiled: March 27, 2009Date of Patent: July 5, 2011Assignee: Affinergy, Inc.Inventors: Guy Orgambide, Mohmed Anwer, Shrikumar A.
