Anti-FAM193B antibodies are used in the immunodetection of the protein family with sequence similarity 193 member B. In humans, the canonical protein has a reported length of 902 amino acid residues and a mass of 96.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. It is a member of the FAM193 protein family. Synonyms for this target antigen include IRIZIO and protein FAM193B. FAM193B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunofluorescence is the most common application for the FAM193B antibodies listed below. ELISA, Western Blot, and Immunocytochemistry are also common applications.
