Anti-SPANXD antibodies are used in the immunodetection of the protein SPANX family member D. In humans, the canonical protein has a reported length of 97 amino acid residues and a mass of 11 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably expressed in the testis, sperm and a melanoma cell line. It is a member of the SPAN-X protein family. Synonyms for this target antigen include Cancer/testis antigen 11.3, Cancer/testis-associated protein CTp11, Nuclear-associated protein SPAN-Xc, SPANX family, member E, and sperm protein associated with the nucleus on the X chromosome D. ELISA is a widely used application for the SPANXD antibodies listed below. In addition, Western Blot is also a common application.
