Anti-ATP5PB antibodies are used in the immunodetection of the protein ATP synthase peripheral stalk-membrane subunit b. In humans, the canonical protein has a reported length of 256 amino acid residues and a mass of 28.9 kDa. Its subcellular localization is in the mitochondria. It is notably widely expressed in many tissue types. It is a member of the Eukaryotic ATPase B chain protein family. Synonyms for this target antigen include PIG47, ATP synthase F(0) complex subunit B1, mitochondrial, ATP synthase B chain, mitochondrial, and ATP5F1. ATP5PB gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ATP5PB antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
