Anti-ATF4 (phospho S245) Antibody

This rabbit polyclonal reagent from Antibodies.com is raised against activating transcription factor 4 (ATF4) when phosphorylated at serine 245, a modification associated with activation of the integrated stress response and downstream translational control under endoplasmic reticulum stress, amino acid limitation, and oxidative challenge. Supplied as a 50 µl aliquot of unconjugated IgG, the antibody is validated for Western blot and immunohistochemistry on human samples and is intended for research use only, supporting studies of unfolded protein response signaling, eIF2α pathway activity, and stress-responsive gene expression in cell and tissue models.
