Anti-EIF2S2 antibodies are used in the immunodetection of the protein eukaryotic translation initiation factor 2 subunit beta. In humans, the canonical protein has a reported length of 333 amino acid residues and a mass of 38.4 kDa. It is notably widely expressed in many tissue types. A member of the EIF-2-beta/eIF-5 protein family, EIF2S2 is known to be involved with in utero embryonic development and male gonad development. Synonyms for this target antigen include EIF2B, PPP1R67, eIF-2-beta, eukaryotic translation initiation factor 2 subunit 2, and EIF2. EIF2S2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of EIF2S2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
