Technical Data
A1059-53C
Aggrecan (Proteoglycan, PG, AGC 1, Aggrecan 1, Antigen identified by monoclonal A0122, Cartilage specific proteoglycan core protein, Chondroitin sulfate proteoglycan core protein 1, CSPCP, CSPG1, CSPGCP, Large aggregating proteoglycan, MSK16, SEDK)
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.

A1059-53C 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.

Applications:
Suitable for use in Western Blot and ELISA. Other applications not tested.

Recommended Dilutions:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Immunogen:
Synthetic peptide corresponding to FFGVGGEEDC from human Aggrecan, conjugated to KLH.
Purity:
Purified by Protein A affinity chromatography.
Form
Supplied as a liquid in PBS, pH 7.6, 0.1% sodium azide
Specificity:
Recognizes human Aggrecan, a neo-epitope on polypeptides with N-terminal FFGVG Sequences. By Western Blot, specifically detects G2 fragments derived from an aggrecan G1-G2 substrate digested with stromelysin, collagenase, gelatinase and matrilysin, but does not 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
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
