Anti-FAM181B antibodies are used in the immunodetection of the protein family with sequence similarity 181 member B. In humans, the canonical protein has a reported length of 426 amino acid residues and a mass of 42.7 kDa. It is notably expressed in the hippocampus, cerebral cortex, and caudate. It is a member of the FAM181 protein family. Synonyms for this target antigen include protein FAM181B. FAM181B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunohistochemistry is the most common application for the FAM181B antibodies listed below. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
