Proteoglycans are categoried depending upon the nature of their glycosaminoglycan chains (chondroitin sulfate, dermatan sulfate, heparan sulphate and keratan sullfate) as well as characterized by size.
Aggrecan is a large aggregating proteoglycan of articular cartilage. It is found also in aorta tissue, discs, tendons and in the perineuronal net. It is responsible for hydrating cartilage, giving it compressibility and resiliance during joint loading, thereby playing a major role in the normal function of cartilage. Depletion of glycosaminoglycan bearing aggrecan fragments is one of the earliest events in cartilage destruction.

Technical Notes:
This antibody should work in IHC on formalin- or paraformaldehyde-fixed paraffin embedded
sections as well as either alcohol-fixed frozen sections or un-fixed snap-frozen sections.
Samples are usually deglycosylated using 0.01 Units Chondroitinase ABC (Sigma), 0.01
Units Keratanase (Seikagaku) and 0.0001 Units Keratanase II (Seikagaku) per 10μg S-GAG
of non-deglycosylated aggrecan for optimal epitope recognition in SDS-PAGE and immunohistochemistry.
