Abstract: The present disclosure provides methods and/or kits for detecting an analyte in a sample. Some embodiments provide a method for detecting a non-nucleic acid analyte in a sample using a solid substrate comprising a bound immobilisation agent and an antibody capture agent and a detectable agent, which can bind to the analyte. The antibody capture agent comprises, at a plurality of sites, a ligand for the immobilisation agent. A complex between the analyte, the antibody capture agent and a detectable agent is formed and immobilised on the solid substrate by binding between the immobilisation agent and the ligand. In some embodiments, the ligand and the immobilisation agent are a binding pair comprising a peptide tag and an anti-peptide tag antibody.
