Product Details
Background
Aggrecan also known as cartilage-specific proteoglycan core protein (CSPCP) or chondroitin sulfate proteoglycan 1 is a protein that is encoded by the ACAN gene. The encoded protein is an integral part of the extracellular matrix in cartilaginous tissue and it withstands compression in cartilage. The human form of the protein is 2316 amino acids long (approximately 250 kDa) and can be expressed in multiple isoforms due to alternative splicing. Aggrecan exhibits a bottlebrush structure, in which chondroitin sulfate and keratan sulfate chains are attached to an extended protein core. The synthesis and degradation of aggrecan are being investigated for their roles in cartilage deterioration during joint injury, disease, and aging. It contains three interglobular domains (IGDs), G1, G2, and G3 that are involved in aggregation, hyaluronan binding, cell adhesion, and chondrocyte apoptosis. Aggrecan fragments from articular cartilage are released into the synovial fluid at all stages of human osteoarthritis as a result of cleavage by aggrecanase and MMP activity. Antibodies BC-3 and BC-4 can be used to detect these neo epitopes of Aggrecanase (ARGSVXXX) and MMP (XXXVDIPEN), respectively.

Data

Western blot analysis of Aggrecan expression in CT26 (A), C6 (B), Hela (C) whole cell lysates. (Predicted band size: 261 kD; Observed band size: 261 kD)

Immunohistochemical analysis of Aggrecan staining in human lung cancer formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

Immunofluorescent analysis of Aggrecan staining in C6 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a hidified chamber. Cells were washed with PBST and incubated with a AF488-conjugated secondary antibody (green) in PBS at room temperature in the dark. Phalloidin - AF594 was used to stain Actin filaments (red). DAPI was used to stain the cell nuclei (blue).
