Anti-ATF2 (Ab-69 or 51) Antibody

ATF2 (Activating Transcription Factor 2) is a member of the ATF/CREB transcription factor family that mediates stress-activated gene expression, DNA damage response, and chromatin remodeling. Phosphorylation at Thr69 and Thr71 by stress-activated kinases such as JNK and p38 MAPK is a key regulatory event for ATF2 activity, making the area near amino acids 69 and 51 an important epitope for studying these pathways.

This rabbit polyclonal reagent from Antibodies.com is raised against the region surrounding amino acid positions 69 and 51 of human ATF2 and is supplied as 100 µl of unconjugated antisera. It is validated for Western blot (WB) and immunohistochemistry (IHC) applications and shows reactivity with Human, Mouse, and Rat samples, supporting cross-species work in cell line and tissue models.

The unconjugated format allows flexible pairing with HRP-, fluorophore-, or biotin-conjugated secondary reagents, and the antibody is provided in a standard storage buffer suitable for repeated use across multiple immunoblotting and tissue-section staining experiments. Researchers studying CRE-dependent transcription, MAPK cascade signaling, stress-induced apoptosis, or transcription factor post-translational modification commonly use this primary antibody at working dilutions optimized for their detection system.
