These HOA ELISA kits are immunodetection tools for measuring the levels of HOA in biological samples. HOA is an alias of the human MATN3 gene, which encodes the protein, matrilin 3. Notably, HOA is known to play a role in cartilage development and extracellular matrix organization, among other functions. 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 and EDM5.
