The OS2 ELISA kits listed below are analytical tools for measuring concentrations of OS2 in various samples. OS2 is an alternative name for the human MATN3 gene, which encodes the protein, matrilin 3. It has been mentioned that OS2 plays a role in cartilage development and extracellular matrix organization, among other functions. Structurally, the MATN3 protein is 486 amino acid residues in length and 52.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is found to be preferentially expressed in cartilaginous tissues, such as vertebrae, ribs and shoulders. Other names for this target antigen include DIPOA, EDM5, and HOA. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
