Anti-MSI1 antibodies are used in the immunodetection of the protein musashi RNA binding protein 1. In humans, the canonical protein has a reported length of 362 amino acid residues and a mass of 39.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably expressed in fetal kidney, brain, liver and lung, and in adult brain and pancreas. A member of the Musashi protein family, MSI1 is known to be involved with nervous system development and epithelial cell differentiation. Synonyms for this target antigen include musashi-1, musashi1, and RNA-binding protein Musashi homolog 1. MSI1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 70 citations in the literature describe the use of MSI1 antibodies in research. Western Blot is a widely used application for these antibodies. Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
