Anti-EIF4A2 antibodies are used in the immunodetection of the protein eukaryotic translation initiation factor 4A2. In humans, the canonical protein has a reported length of 407 amino acid residues and a mass of 46.4 kDa. Up to 2 different isoforms have been reported for this protein. A member of the DEAD box helicase protein family, EIF4A2 is an ATP-dependent RNA helicase which is a subunit of the eIF4F complex involved in cap recognition and is required for mRNA binding to ribosome. Synonyms for this target antigen include DDX2B, EIF4A, EIF4F, eIF-4A-II, eIF4A-II, and BM-010. EIF4A2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 130 citations in the literature describe the use of EIF4A2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
