Anti-MSC antibodies are used in the immunodetection of the protein musculin. In humans, the canonical protein has a reported length of 206 amino acid residues and a mass of 22.1 kDa. Its subcellular localization is in the nucleus. It is reported to be expressed in lymphoid tissues, B-cell lines and activated B-cells. MSC is known to be involved with the regulation of transcription and skeletal muscle tissue development. Synonyms for this target antigen include ABF1, MYOR, bHLHa22, activated B-cell factor 1, homolog of mouse musculin, activated B-cell factor-1, and ABF-1. MSC 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 MSC antibodies listed below. ELISA and Immunohistochemistry are also common applications.
