Anti-MLF1 antibodies are used in the immunodetection of the protein myeloid leukemia factor 1. In humans, the canonical protein has a reported length of 268 amino acid residues and a mass of 30.6 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 the testis, ovary, skeletal muscle, heart, kidney and colon. A member of the MLF protein family, MLF1 is known to be involved in lineage commitment of primary hemopoietic progenitors by restricting erythroid formation and enhancing myeloid formation. Synonyms for this target antigen include myelodysplasia-myeloid leukemia factor 1 and testis tissue sperm-binding protein Li 49e. MLF1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some MLF1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
