Anti-TBG antibodies enable researchers to detect and measure the TBG antigen in biological samples. This target is a reported synonym of the SERPINA7 gene, which encodes serpin family A member 7. The human version of TBG has a canonical amino acid length of 415 residues and a protein mass of 46.3 kilodaltons. It is reported to be a secreted protein. This target antigen may also be known as TBGQTL.
