Anti-FHL1 antibodies are used in the immunodetection of the protein four and a half LIM domains 1. In humans, the canonical protein has a reported length of 323 amino acid residues and a mass of 36.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 5 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the endometrium and lung. FHL1 is believed to have an involvement in muscle development or hypertrophy. The FHL1 gene has been associated with the disease, Emery-Dreifuss muscular dystrophy. Synonyms for this target antigen include FHL1A, FHL1B, FLH1A, KYOT, RBMX1A, RBMX1B, SLIM, and FCMSU. FHL1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of FHL1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
