Anti-OS2 antibodies enable researchers to detect and measure the OS2 antigen in biological samples. This target is a reported synonym of the MATN3 gene, which encodes matrilin 3. This protein is known to function in cartilage development and extracellular matrix organization, among other biological roles. The human version of OS2 has a canonical amino acid length of 486 residues and a protein mass of 52.8 kilodaltons, although 2 isoforms have been identified. It is reported to be a secreted protein. Other names for this target antigen include DIPOA, EDM5, and HOA. Indicated applications for OS2 antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
