| 摘要 |
A method of binding a recognition element to a gold surface (24) comprising the steps of attaching a GBP-AP protein (10) to a gold surface (24), digesting away the AP domain of the protein (10) with a proteolytic enzyme from the bound GBP domain (12) attached to the gold surface (24), and attaching a recognition element, such as Protein A (52) or an antibody 72, antigen, nucleic acid or other binding partner to the GBP domain (12) which remains on the gold surface (24), is disclosed.
