DETECTION OR QUANTIFICATION OF AGGRECAN AND ITS FRAGMENTS

摘要

An immunoassay for aggrecan and/or aggrecan derived fragments comprises contacting a sample with an immunological binding partner which has specific binding affinity for the G2 domain of aggrecan at least when bearing keratan sulphate chains, and determining the existence or amount of specific binding of the immunological binding partner, which may be conducted as a sandwich assay using a first antibody that binds an N-terminal amino acid sequence comprising FFGVG.. and a second antibody that binds an N-terminal amino acid sequence comprising ARGS.
