Anti-FBRSL1 antibodies are used in the immunodetection of the protein fibrosin like 1. In humans, the canonical protein has a reported length of 1045 amino acid residues and a mass of 110.9 kDa. It is notably expressed in the hippocampus, colon, cerebral cortex, cerebellum, and caudate. It is a member of the AUTS2 protein family. Synonyms for this target antigen include AUTS2-like protein, HBV X-transactivated gene 9 protein, HBV XAg-transactivated protein 9, and fibrosin-1-like protein. FBRSL1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the FBRSL1 antibodies listed below. ELISA, Flow Cytometry, and Immunofluorescence are also common applications.
