Recombinant Human COL9A1 Protein (His Tag)

COL9A1; which is short for Collagen alpha-1 (IX) chain; is a 921 aa. protein. It is a secreted protein; and exists in extracellular space and extracellular matrix. This protein is a heterotrimer of an alpha 1 (IX) ; an alpha 2 (IX) and an alpha 3 (IX) chain.Each subunit is composed of three triple-helical domains interspersed with non-collagenous domains. The globular domain at the N-terminus of type IX collagen molecules represents the NC4 domain which may participate in electrostatic interactions with polyanionic glycosaminoglycans in cartilage. It ia a structural component of hyaline cartilage and vitreous of the eye.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
