Anti-FAM203B antibodies enable researchers to detect and measure the FAM203B antigen in biological samples. This target is a reported synonym of the HGH1 gene, which encodes HGH1 homolog. The human version of FAM203B has a canonical amino acid length of 390 residues and a protein mass of 42.1 kilodaltons. It is reported to be widely expressed in many tissue types. Other names for this target antigen include BRP16, BRP16L, and C8orf30A.
