Abstract

A biosensor apparatus for detecting a binding event between a ligand and receptor. The apparatus includes a biosensor surface and surface-bound two-subunit heterodimer complexes composed of first and second, preferably oppositely charged peptides that together form an .alpha.-helical coiled-coil heterodimer. The first peptide is attached to the biosensor surface, and the second peptide carries the ligand, accessible for binding by a ligand-binding agent. Binding of anti-ligand binding agent to the surface-bound ligand is detected by a suitable detector. A ligand-specific biosensor surface can be readily prepared from a universal template containing the first charged peptide, by addition of a selected ligand attached to the second peptide.
