Abstract: Peptides which bind to selected receptor molecules are identified by screening libraries which encode a random or controlled collection of amino acids. Peptides encoded by the libraries are expressed as fusion proteins of bacteriophage coat proteins, and bacteriophage particles are then screened against the receptors of interest. Peptides having a wide variety of uses, such as therapeutic or diagnostic reagents, may thus be identified without any prior information on the structure of the expected ligand or receptor molecule.

Abstract: The peptide HITWDQLWNVMN (SEQ ID NO: 4) and related peptides and peptidomimetics bind to endothelial leukocyte adhesion molecule 1 and block the binding of leukocytes to this important receptor and so can be used to ameliorate the detrimental effects of certain disease conditions.

Abstract: Disclosed are peptides and peptide mimetics that bind selectins, including endothelial leukocyte adhesion molecule 1 (ELAM-1). Such peptides and peptide mimetics are useful in methods for blocking adhesion of leukocytes to the selectins for the purpose of inhibiting inflammation as well as in diagnostic methods employing labeled peptides and peptide mimetics that bind selectins for the purpose of determining the site of inflammation in mammals which inflammation is mediated by the presence of one or more selectins.

Abstract: Nucleotide sequences encoding proteins of interest are isolated from DNA libraries using bacteriophage to link the protein to the sequence which encodes it. DNA libraries are prepared from cells encoding the protein of interest and inserted into or adjacent to a coat protein of a bacteriophage vector, or into a sequence encoding a protein which may be linked by means of a ligand to a phage coat protein. By employing affinity purification techniques the phage particles containing sequences encoding the desired protein may be selected and the desired nucleotide sequences obtained therefrom. Thus, for example, novel proteins such as monoclonal antibodies may be produced and conventional hybridoma technology avoided.
