Anti-MAGEB4 antibodies are used in the immunodetection of the protein MAGE family member B4. In humans, the canonical protein has a reported length of 346 amino acid residues and a mass of 38.9 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the testis. MAGEB4 is known to be involved with the regulation of transcription. Synonyms for this target antigen include melanoma-associated antigen B4, MAGE-B4 antigen, cancer/testis antigen family 3, member 6, melanoma antigen family B, 4, melanoma antigen family B4, and CT3.6. MAGEB4 gene orthologs have been reported in the mouse, rat and chimpanzee species. Some MAGEB4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
