Anti-GPI-80 antibodies enable researchers to detect and measure the GPI-80 antigen in biological samples. This target is a reported synonym of the VNN2 gene, which encodes vanin 2. This protein is known to function in metabolic processes, among other biological roles. The human version of GPI-80 has a canonical amino acid length of 520 residues and a protein mass of 58.5 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include FOAP-4 and GPI-80. Indicated applications for GPI-80 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
