Provided below are ELISA kits targeting tenascin C, a human protein encoded by TNC. This protein is 2201 amino acids long, with a mass of 240.9 kDa, and is a member of the Tenascin family. 6 isoforms have been identified. This is reported to be a secreted protein. There is a noted implication in Deafness, autosomal dominant, 56. Other alias names for this protein include: tenascin, GP 150-225, cytotactin, deafness autosomal dominant 56, hexabrachion (tenascin), myotendinous antigen, and neuronectin. ELISA kits are available that are reactive to human, mouse, rat, bovine, chicken, primate, guinea pig, fish, plant, and other mammalian variants of the target antigen.
