Date Mar. 17, 1994A filamentous phage is described comprising a matrix that includes a heterologous polypeptide fused to a first filamentous phage coat protein membrane anchor and a heterodimeric receptor comprised of first and second receptor polypeptides, wherein one of the receptor polypeptides is fused to a second filamentous phage coat protein membrane anchor. Filamentous phage expressing anchored heterodimeric receptors and dimers of heterologous polypeptides where a first subunit of the dimer is fused to a coat protein membrane anchor and the second subunit of the dimer is soluble heteromeric receptor are also described.
