Aplicación

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.

Acciones bioquímicas o fisiológicas

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.

Componentes

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.

Precaución

Store this product at -20°C. Stored as supplied, this powder shows little decomposition in 3 years when stored properly.

Nota de preparación

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.

Aggrecan, the predominant large proteoglycan of cartilage, is a multidomain macromolecule with each domain contributing specific functional properties. One of the domains contains the majority of the keratan sulfate (KS) chain substituents and a protein segment with a proline-rich hexapeptide

The breakdown of aggrecan in cartilage is, in part, mediated by an enzyme named aggrecanase that cleaves within the interglobular domain of the molecule between a glutamic residue and an alanine residue. Although the enzyme cleavage site has been identified

The proteoglycan aggrecan is a major component of cartilage, and degradation of aggrecan is associated with aging and a number of pathological conditions. To investigate the effects of the accumulation of G1 domain from degraded aggrecan, we overexpressed the G1

A major feature of cartilage deterioration during joint injury and disease is aggrecan degradation and the loss of proteoglycan. Most of the degraded fragments are released into the circulatory system except the G1 domain which accumulates locally in the synovial

The rates of incorporation of radiolabelled leucine into aggrecan and link protein have been measured in human articular cartilage of different ages. Aggrecan and link protein were purified in the A1 fraction of CsCl gradients as a result of their
