Anti-VAX2 antibodies are used in the immunodetection of the protein ventral anterior homeobox 2. In humans, the canonical protein has a reported length of 290 amino acid residues and a mass of 30.9 kDa. Its subcellular localization is in the nucleus. A member of the EMX homeobox protein family, VAX2 is reported to be a transcription factor that may function in dorsoventral specification of the forebrain. Synonyms for this target antigen include DRES93. VAX2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Some VAX2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
