  • Publication number: 20110117165
    Abstract: Compositions and methods are provided for promoting bone growth. An implantable bone graft material is provided comprising a resorbable ceramic and a resorbable polymer, wherein the polymer comprises a covalently attached BMP binding peptide. In addition, an implantable bone graft material is provided consisting essentially of a resorbable ?-TCP and a resorbable polymer, wherein the ?-TCP has a total porosity of about 50% or greater and wherein the ?-TCP has a particle size ranging from about 100 micron to about 300 micron. The implantable bone graft materials are useful for promoting bone growth in a subject.

  • Patent number: 7807624
    Abstract: The present invention provides compositions and methods for an improved coating for medical devices. Provided is a biofunctional coating composition comprising at least one binding domain that has binding specificity for a surface material of a medical device, and at least one binding domain that has binding specificity for cells of endothelial cell lineage. Methods for coating a surface of a medical device, and for manufacturing of a medical device, comprise contacting the surface to be coated with the biofunctional coating material in an amount effective to form a coating, and may further comprise contacting the coated surface with cells of endothelial cell lineage to bind the cells of endothelial cell lineage to the coated surface.

  • Publication number: 20030003489
    Abstract: The biased residue of an expressible biased peptide library is conveniently altered, without synthesizing a new DNA mixture, by using a DNA encoding said peptide which includes a suppressible stop codon, said codon encoding the biased residue, whereby the amino acid appearing at the biased position may be altered simply by introducing the same DNA mixture into a different suppressor strain.
