Anti-EIF5 antibodies are used in the immunodetection of the protein eukaryotic translation initiation factor 5. In humans, the canonical protein has a reported length of 431 amino acid residues and a mass of 49.2 kDa. It is notably widely expressed in many tissue types. A member of the EIF-2-beta/eIF-5 protein family, EIF5 is known to catalyze the hydrolysis of GTP bound to the 40S ribosomal initiation complex (40S.mRNA.Met-tRNA[F].eIF-2.GTP) with the subsequent joining of a 60S ribosomal subunit resulting in the release of eIF-2 and the guanine nucleotide. Synonyms for this target antigen include EIF-5A. EIF5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of EIF5 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
