| Background | The translation initiation factor EIF2 catalyzes the first regulated step of protein synthesis initiation, promoting the binding of the initiator tRNA to 40S ribosomal subunits. Binding occurs as a ternary complex of methionyl-tRNA, EIF2, and GTP. EIF2 is composed of 3 nonidentical subunits, the 36-kD EIF2-alpha subunit (EIF2S1), the 38-kD EIF2-beta subunit (EIF2S2; MIM 603908), and the 52-kD EIF2-gamma subunit (EIF2S3; MIM 300161). The rate of formation of the ternary complex is modulated by the phosphorylation state of EIF2-alpha (Ernst et al., 1987 [PubMed 2948954]). |

1.The species of antibody reactivity should be the sample species that can be matched normally after Abbkine R&D experts have passed strict scientific verification. If your sample is not within the range of reactivity, in order to improve the efficiency and results of your experiment, it is not suggested to try other species. Otherwise, it may lead to sample mismatch and affect the effect of your experiment.
2.Please aliquot the antibody received as soon as possible and store it at -20℃, avoid repeated freezing and thawing, and use it within one year.
