SPANXD ELISA kits are immunoassay tools for the measurement of the protein SPANX family member D, which is encoded by the SPANXD gene in humans. The canonical protein structure is reported to have an amino acid length of 97 residues, a mass of 11 kDa, and is a member of the SPAN-X protein family. It is known to be localized in the nucleus and cytoplasm and is notably expressed in testis, sperm and a melanoma cell line. Other alias names for this target 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.
