Anti-STEAP1B antibodies are used in the immunodetection of the protein STEAP family member 1B. In humans, the canonical protein has a reported length of 245 amino acid residues and a mass of 28.8 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. It is a member of the STEAP protein family. Synonyms for this target antigen include STEAP family protein MGC87042. STEAP1B gene orthologs have been reported in the mouse, rat and chimpanzee species. These STEAP1B antibodies are widely used in Western Blot experiments, among other applications.
