Product Name :  Human Recombinant Collagen alpha-1(IX) chain (from Cells)
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.

FormulationLyophilized from a 0.2 um filtered solution of 20mM PB,150mM NaCl, pH7.4. Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the Lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Molecular weight33.8 kD
Storage conditionsLyophilized protein should be stored at ?20 °C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7 °C for 2-7 days. Aliquots of reconstituted samples are stable at ?20 °C for 3 months.
