Anti-MAD1L1 antibodies are used in the immunodetection of the protein mitotic arrest deficient 1 like 1. In humans, the canonical protein has a reported length of 718 amino acid residues and a mass of 83.1 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. A member of the MAD1 protein family, MAD1L1 is a known component of the spindle-assembly checkpoint that prevents the onset of anaphase until all chromosomes are properly aligned at the metaphase plate. Synonyms for this target antigen include MVA7, PIG9, TP53I9, TXBP181, mitotic spindle assembly checkpoint protein MAD1, and MAD1. MAD1L1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 80 citations in the literature describe the use of MAD1L1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
