    摘要: Provided is a method of attaching a substance to a surface, which method comprises contacting a surface comprising amine reactive groups with a substance labelled with a peptide tag such that the substance is covalently attached to the surface via the peptide tag, wherein the peptide tag comprises one or more histidine residues, one of which is a terminal histidine residue having a free N-terminal amino group. Also provided is a method of processing or analysis which comprises a method of attaching a substance to a surface as detailed above and comprises one or more further steps of processing or analysing the substance. The present invention further provides a method of processing or analysis comprising the steps of: a) attaching a substance to a surface by a method as defined above b) contacting the surface with a sample comprising an analyte in order that the analyte in the sample binds to the substance attached to the surface; and c) processing and/or analysing the analyte
