These Ia2 ELISA kits are immunodetection tools for measuring the levels of Ia2 in biological samples. Ia2 is an alias of the human PTPRN gene, which encodes the protein, protein tyrosine phosphatase receptor type N. Notably, Ia2 is known to play a role in carbohydrate metabolism and homeostasis and the regulation of transcription, among other functions. The PTPRN protein is 979 amino acid residues in length and 105.8 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the cytoplasmic vesicles and cell membrane of the cell. This protein is known to be O-glycosylated, N-glycosylated, sumoylated and cleaved. Other names for this target antigen include IA-2. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
