| Application: | Aggrecan is a critical component for cartilage structure and the function of joints. Its synthesis and degradation are being studied for their roles in cartilage deterioration during joint injury disease and aging. |
| Biochem/physiol Actions: | This molecule produces a rigid, reversibly deformable gel that resists compression. It combines with hyaluronic acid to form very large macromolecular complexes that have an increased hydrohynamic volume and a significant increase (30-40%) in the relative viscosity of the solution. |
| Disclaimer: | Store this product at -20°C. Stored as supplied, this powder shows little decomposition in 3 years when stored properly. |
| Other Notes: | Aggrecan is a major structural proteoglycan of the cartilage extracellular matrix. It is a large proteoglycan, with a molecular weight greater than 2,500 kDa composed of approximately 100-150 glycosaminoglycan chains attached to a core protein. The majority of these glycosaminoglycan chains are chondroitin/dermatan sulfate. Aggrecan contains three globular domains, G1, G2, and G3, which are involved in aggregation and hylauronan binding, cell adhesion and chondrycte apoptosis. |
| Packaging: | 1 mg in glass bottle |
| Preparation Note: | This product is extracted from articular cartilage, chematographically purified, dialyzed against water, and 0.2 μm filtered prior to lyophilization. Once lyophilized, this powder is essentially salt-free. The product is soluble in water at 2 mg/mL. |
