The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site. ATM (phospho-Ser1981) antibody detects endogenous levels of ATM only when phosphorylated at serine 1981.
Purification
Immunoaffinity chromatography.
Immunogen
The antiserum was produced against synthesized phosphopeptide derived from human ATM around the phosphorylation site of serine 1981 (E-G-SP-Q-S).

ATM is a 370 kDa nuclear phosphoprotein involved in the autosomal recessive disease Ataxia Telangiectasia (AT). ATM belongs to a novel family of proteins associated with cell cycle regulation, apoptosis, and response to DNA damage repair (DNA damage caused by such things as ionizing irradiation activates ATM kinase). The C terminal region has extensive homology to the catalytic domains of Phosphatidylinositol 3 kinases (PI3 kinases).Synonyms: A-T mutated, ATDC, Ataxia telangiectasia mutated, Serine-protein kinase ATM, TEL1, TELO1
