Anti-Alpha-1-fetoprotein antibodies enable researchers to detect and measure the Alpha-1-fetoprotein antigen in biological samples. This target is a reported synonym of the AFP gene, which encodes alpha fetoprotein. This protein is known to function in metabolic processes, among other biological roles. The human version of Alpha-1-fetoprotein has a canonical amino acid length of 609 residues and a protein mass of 68.7 kilodaltons. It is reported to be a secreted protein. Other names for this target antigen include AFPD, FETA, and HPAFP. Western Blot is a widely used application for the Alpha-1-fetoprotein antibodies listed below. In addition, ELISA is also a common application.
