Anti-ATF2 (phospho T71 + T53) Antibody

The antibody targets ATF2 phosphorylated at threonine 71 and threonine 53, two residues whose modification is driven by stress-activated kinases in the JNK and p38 MAPK pathways and is closely tied to ATF2's dimerization with Jun family partners and subsequent transcriptional output. This polyclonal reagent, raised in rabbit and supplied by Antibodies.com as an IgG formulation at 100 µl per vial, is unconjugated and validated for western blot and immunohistochemistry across human, mouse, and rat samples. Researchers studying DNA damage response, oxidative stress signalling, or oncogenic transformation commonly use phospho-specific ATF2 antibodies to distinguish the activated, transcriptionally engaged pool of ATF2 from total protein levels.
