Zinc oxide-binding antibody

Patent Granted Disclosed are: a zinc oxide-binding antibody which has high stability and a high binding activity; and a high-throughput sensing technique such as a biosensor, which utilizes the antibody. Specifically disclosed are: a peptide-grafted antibody having an zinc oxide-recognizing peptide in a CDR H-1 region of a camel antibody; and a solid substrate (a biosensor, a protein chip, or the like) which has a zinc oxide layer having the antibody immobilized thereon.
