Our Anti-ATF2 (Thr52) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human and mouse ATF2 (Thr52) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of UACC903 melanoma cell line lysate (DMSO) showing specific immunolabeling of the ~ 72 kDa ATF2 protein phosphorylated at Thr52. Immunolabeling is reduced by treatment of the lysate with the PKC catalytic inhibitor Gö6850. Image courtesy of Eric Lau and Ze’ev Ronai.

Bulk Order Anti-ATF2 (Thr52) Antibody
The transcription factor ATF2 is a member of the ATF/CREB family of leucine zipper proteins. In response to stress stimuli, it activates a variety of gene targets that are involved in oncogenesis, and has been correlated with maintenance of a cancer cell phenotype (Vlahopoulos et al., 2008). Inhibiting ATF2 impedes melanoma development and elicits tumor suppressor function (Bhoumik et al., 2008). To act as a tumor suppressor, ATF2 must localize at the mitochondria, and phosphorylation at Thr-52 by PKCε regulates this translocation (Lau et al., 2012).
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Thr52 of human ATF2, conjugated to keyhole limpet hemocyanin (KLH).
Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
Prepared from rabbit serum by affinity purification via sequential chromatography on phospho and non-phosphopeptide affinity columns.
10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.
Specific for endogenous levels of the ~72 kDa ATF2 protein phosphorylated at Thr52. Immunolabeling of the ATF2 band is reduced by treatment of the cells with the PKC catalytic inhibitor Gö6850.
Western blots performed on each lot.
