Anti-EIF2S1 Antibody [Assigned #A9905]

Mouse monoclonal antibody targeting EIF2S1 (Eukaryotic Translation Initiation Factor 2 Subunit Alpha), a key regulator of translation initiation and the integrated stress response. Phosphorylation of EIF2S1 at Ser51 is a hallmark of cellular stress signaling, making this reagent useful for studying translation regulation, ER stress, viral infection responses, and pathways involving upstream kinases such as PERK, GCN2, HRI, and PKR.

The unconjugated IgG reagent, supplied by Antibodies.com, is validated for Western Blot, Immunofluorescence, and Immunoprecipitation across human, mouse, and rat samples. It is raised in mouse and provided in a 200µl volume suitable for multiple experiments. Researchers investigating stress granule formation, ATF4-mediated transcription, or neurodegeneration use this antibody to monitor EIF2S1 expression and phosphorylation status in cell lysates and tissue sections.
