Anti-C11orf8 antibodies enable researchers to detect and measure the C11orf8 antigen in biological samples. This target is a reported synonym of the MPPED2 gene, which encodes metallophosphoesterase domain containing 2. The human version of C11orf8 has a canonical amino acid length of 294 residues and a protein mass of 33.4 kilodaltons, although 2 isoforms have been identified. Other names for this target antigen include 239FB and 239FB.
