Anti-ELK1 antibodies are used in the immunodetection of the protein ETS transcription factor ELK1. In humans, the canonical protein has a reported length of 428 amino acid residues and a mass of 44.9 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the ETS protein family, ELK1 is reported to be a transcription factor that binds to purine-rich DNA sequences. Synonyms for this target antigen include ELK1, ETS transcription factor, ELK1, member of ETS oncogene family, ETS-like gene 1, tyrosine kinase (ELK1) oncogene, and ETS domain-containing protein Elk-1. ELK1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Over 190 citations in the literature describe the use of ELK1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
