Anti-NT5C3B antibodies are used in the immunodetection of the protein 5'-nucleotidase, cytosolic IIIB. In humans, the canonical protein has a reported length of 300 amino acid residues and a mass of 34.4 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Pyrimidine 5'-nucleotidase protein family, NT5C3B is known to be involved with metabolic processes. Synonyms for this target antigen include 5'-nucleotidase, cytosolic III-like, 7-methylguanosine nucleotidase, N(7)-methylguanylate 5'-phosphatase, cN-III-like protein, and 7-methylguanosine phosphate-specific 5'-nucleotidase. NT5C3B gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some Nt5c3b antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
