Recombinant Human COL9A2 protein (NP_001843.1) is produced in Sia-Adjusted Human Cell Lines. This expression system is used for the production of glycoproteins and antibodies with different sialylation degree.
This gene encodes one of the three alpha chains of type IX collagen, the major collagen component of hyaline cartilage. Type IX collagen, a heterotrimeric molecule, is usually found in tissues containing type II collagen, a fibrillar collagen. This chain is unusual in that, unlike the other two type IX alpha chains, it contains a covalently attached glycosaminoglycan side chain.
