Anti-TN antibodies enable researchers to detect and measure the TN antigen in biological samples. This target is a reported synonym of the CLEC3B gene, which encodes C-type lectin domain family 3 member B. The human version of TN has a canonical amino acid length of 202 residues and a protein mass of 22.5 kilodaltons. It is reported to be a secreted protein that is notably expressed in the testis.
