Anti-ATF2 (phospho T73 + T55) Antibody

This unconjugated rabbit polyclonal antibody recognizes ATF2 (Activating Transcription Factor 2) only when both threonine 73 and threonine 55 are phosphorylated. Because the dual-phospho requirement is built into the binding site, the reagent reports the signaling-active pool of ATF2 rather than total protein levels, and it is used in studies of DNA damage, oxidative stress, and inflammatory signaling where the transcription factor is activated by stress kinases.

From Antibodies.com, the antibody is supplied as a 100 µl vial of IgG in polyclonal format and is validated for Western Blot (WB), Immunohistochemistry (IHC), and Immunofluorescence (IF) workflows. It has been tested on human, mouse, and rat samples, supporting comparative work across model organisms in cell signaling, neuroscience, and oncology research. Because binding is phospho-specific, samples should be processed with phosphatase inhibitors to maintain the modified epitopes before immunodetection.
