Anti-FAM219A antibodies are used in the immunodetection of the protein family with sequence similarity 219 member A. In humans, the canonical protein has a reported length of 185 amino acid residues and a mass of 20.4 kDa. Up to 7 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. It is a member of the FAM219 protein family. Synonyms for this target antigen include protein FAM219A and uncharacterized protein C9orf25. FAM219A gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is the most common application for the FAM219A antibodies listed below. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
