Abstract:
1. A method for detecting the presence of a preselected ligand in a sample comprising the steps of: a) admixing a sample suspected to contain a preselected ligand with a ligand-binding heterodimeric antibody comprising first and second polypeptides wherein said first polypeptide is fused to a filamentous phage membrane cpVIII anchor domain, wherein said ligand-binding heterodimeric antibody binds to said preselected ligand under binding conditions sufficient for said ligand-binding heterodimeric antibody to bind said ligand and form a ligand-antibody complex; and b) detecting the presence of said ligand-antibody complex or said ligand-binding heterodimeric antibody in said complex.
