Anti-C11orf57 antibodies enable researchers to detect and measure the C11orf57 antigen in biological samples. This target is a reported synonym of the NKAPD1 gene, which encodes NKAP domain containing 1. The human version of C11orf57 has a canonical amino acid length of 292 residues and a protein mass of 34.1 kilodaltons, although 3 isoforms have been identified. It is reported to be widely expressed in many tissue types.
