Anti-EIF2S2 (phospho-S67) Antibody

Phosphorylation at serine 67 introduces a regulatory mark on EIF2S2, the beta subunit of eukaryotic translation initiation factor 2 that functions in initiator methionyl-tRNA delivery to the ribosome. This unconjugated rabbit polyclonal antibody from Antibodies.com recognizes the phospho-S67 form of EIF2S2 and is recommended for western blot analysis across human, mouse, and rat sample types. The reagent is supplied as 100 µl at 1 mg/ml in phosphate buffered saline (PBS) with 15 mM sodium azide at approximately pH 7.2, providing enough material for multiple immunoblot experiments. Researchers investigating integrated stress response signaling, translational control in cancer, or host factor interactions during viral replication rely on phospho-specific antibodies like this one to monitor site-specific EIF2S2 modification in whole-cell and tissue lysates. Refrigerate the antibody at 4°C for active use; for extended storage, aliquot and freeze at -20°C to limit freeze-thaw cycles and preserve phospho-specific binding activity.
