Anti-AP3B1 antibodies are used in the immunodetection of the protein adaptor related protein complex 3 subunit beta 1. In humans, the canonical protein has a reported length of 1094 amino acid residues and a mass of 121.3 kDa. Its subcellular localization is in the cytoplasmic vesicles, Golgi, and membrane. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the Adaptor complexes large subunit protein family, AP3B1 is known to be involved with the differentiation of certain cell types. Synonyms for this target antigen include ADTB3A, HPS, HPS2, PE, AP-3 complex subunit beta-1, and ADTB3. AP3B1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of AP3B1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
