Anti-Collagen Type II/COL2A1 Antibody Picoband® Fluoro488 Conjugated

Collagen, type II, alpha 1 (primary osteoarthritis, spondyloepiphyseal dysplasia, congenital), also known as COL2A1, is a human gene that provides instructions for the production of the pro-alpha1 (II) chain of type II collagen. This gene encodes the alpha-1 chain of type II collagen, a fibrillar collagen found in cartilage and the vitreous humor of the eye. Mutations in this gene are associated with achondrogenesis, chondrodysplasia, early onset familial osteoarthritis, SED congenita, Langer-Saldino achondrogenesis, Kniest dysplasia, Stickler syndrome type I, and spondyloepimetaphyseal dysplasia Strudwick type. In addition, defects in processing chondrocalcin, a calcium binding protein that is the C-propeptide of this collagen molecule, are also associated with chondrodysplasia. There are two transcripts identified for this gene.

E.coli-derived human Collagen Type II/COL2A1 recombinant protein (Position: G1217-A1241) . Human COL2A1 shares 92% and 96% amino acid (aa) sequence identity with mouse and rat COL2A1, respectively.
