Western blot - Anti-EIF2B5 (phospho S539) antibody (AB4775)

Peptide Competition : Recombinant eIF-2B episilon treated with lambda phosphatase (1) or treated with GSK-3 beta (lanes 2-5) and added to background extracts were resolved by SDS-PAGE on a 10% Tris-glycine gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4^oC, then were incubated with 0.50 μg/mL ab4775 antibody, following prior incubation with : no peptide (1, 2), the nonphosphopeptide corresponding to the immunogen (3), a generic phophoserine containing peptide (4), or, the phosphopeptide immunogen (5). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and signals were detected using the Tropix WesternStar method. The data show that only the peptide corresponding to ab4775 blocks the antibody signal, thereby demonstrating the specificity of the antibody. The data also show the up-regulation of the ab4775 phospho signal upon stimulation with GSK-3 beta. Pep
