A number of ELISA Kits are available that target IA-2/PTP, an alias of the protein, protein tyrosine phosphatase receptor type N. The human protein, encoded by the gene PTPRN, is a member of the Protein-tyrosine phosphatase family, Receptor class 8 subfamily. The protein's cellular localization is indicated to be nuclear and membrane-associated. Additional synonyms or past names for this protein may include: IA-2, IA-2/PTP, IA2, ICA512, R-PTP-N. Homology is conserved in other species, such as Mouse, Rat, Frog.
