Anti-ARMCX4 antibodies are used in the immunodetection of the protein armadillo repeat containing X-linked 4. In humans, the canonical protein has a reported length of 2290 amino acid residues and a mass of 236 kDa. Its subcellular localization is in the membrane. Up to 3 different isoforms have been reported for this protein. It is a member of the Eutherian X-chromosome-specific Armcx protein family. Synonyms for this target antigen include armadillo repeat-containing X-linked protein 4 and armadillo repeat containing, X-linked 4 pseudogene. ARMCX4 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is a widely used application for the ARMCX4 antibodies listed below. In addition, ELISA is also a common application.
