General description

Aggrecan is also known as aggregating chondroitin sulphate proteoglycan. Aggrecan is the major proteoglycan present in articular cartilage, composing up to 10% of its dry weight. It is responsible for endowing articular with its intrinsic properties of load bearing and compressive forces.

Specificity

Mouse anti-aggrecan is a cleavage-site-specific monoclonal antibody for detecting metalloproteinase-derived aggrecan fragments. The antibody recognizes neo-epitopes on polypeptides with N-terminal FFGVG sequences. This sequence is found at the N-terminus of aggrecan fragments that have been digested with MMPs. By immunoblotting, AF-28 specifically detected G2 fragments derived from an aggrecan G1-G2 substrate digested with stromelysin, collagenase, gelatinase, and matrilysin, but failed to detect G2 fragments obtained from elastase, trypsin, or cathepsin B digests. Undigested G1-G2 was not detected. Competition experiments confirmed that peptides containing internal FFGVG sequences were not detected by the antibody. Clone AF-28 specifically recognizes a neo-epitope on polypeptides with N-terminal FFGVG Sequences. This sequence is found at the N-terminus of aggrecan fragments that have been digested with matrix metalloproteinases.
