Product details

The Human Aggrecan Enzyme-Linked Immunosorbent Assay (ELISA) kit (ab213754) is designed for the quantitative measurement of Human Aggrecan in cell culture supernatants, serum and urine.

The ELISA kit is based on standard sandwich enzyme-linked immunosorbent assay technology. A monoclonal antibody from mouse specific for Aggrecan has been pre-coated onto 96-well plates. Standards (NSO, V20-G675) and test samples are added to the wells, a biotinylated detection monoclonal antibody from mouse specific for Aggrecan is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Human Aggrecan amount of sample captured in plate.

Aggrecan, also known as cartilage-specific proteoglycan core protein (CSPCP) or chondroitin sulfate proteoglycan 1, is a protein that in humans is encoded by the ACAN gene. It is a critical component for cartilage structure and the function of joints. Aggrecan provides intervertebral disc and cartilage with the ability to resist compressive loads. The localized high concentrations of aggrecan provide the osmotic properties necessary for normal tissue function with the GAGs producing the swelling pressure that counters compressive loads on the tissue. This functional ability is dependent on a high GAG/aggrecan concentration being present in the tissue extracellular matrix. Also, Aggrecan plays an important role in the organization of the extracellular spaces between neurons in the brain.

Supplementary information

Aggrecan also known as aggrecan core protein or chondroitin sulfate proteoglycan 1 is a large proteoglycan vital for cartilage structure and function. It has a mass of approximately 250 kDa. Aggrecan is expressed mostly in cartilage regions such as articular cartilage but it might also be found in other connective tissues. The structure of aggrecan consists of a core protein that attaches to glycosaminoglycan chains allowing it to create hydrated gel structures essential for the resilience and load-bearing properties of cartilage.
Biological function summary

Aggrecan plays a significant role in maintaining the structural integrity of cartilage by providing resistance to compression. This proteoglycan is a central component of the extracellular matrix forming large aggregates with hyaluronic acid and link proteins. These aggregates contribute to the cartilage's osmotic properties helping resist compression during joint movement. Aggrecan's structural properties make it necessary for normal joint function and health.

Pathways

Aggrecan interacts within the cartilage development and maintenance frameworks. Specifically it participates in the regulation of the ECM-receptor interaction pathway and the proteoglycans in cancer pathway. Aggrecan functions alongside proteins such as type II collagen to ensure biomechanical properties of the cartilage. Additionally its enzymatic breakdown by aggrecanases like ADAMTS can impact these pathways leading to various physiological effects.

Aggrecan is closely associated with osteoarthritis and intervertebral disc degeneration. In osteoarthritis the loss of aggrecan through enzymatic degradation leads to reduced joint function and increased pain. The breakdown involves aggrecanases and other matrix metalloproteinases resulting in cartilage degradation. Diseases such as intervertebral disc degeneration also link to the reduced presence or altered structure of aggrecan impacting spine health and mobility.

Target data

This proteoglycan is a major component of extracellular matrix of cartilagenous tissues. A major function of this protein is to resist compression in cartilage. It binds avidly to hyaluronic acid via an N-terminal globular region.
