Anti ATM Antibody showing overlay of anti-ATM pS1981 staining. Cells were fixed 15 min after 5 Gy (IR+) of ??irradiation, then labeled with antibody. See Kitagawa et al. for additional details.
Anti ATM Mab with human derived HEK293 cells treated with doxorubicin using Rockland's Protein A Purified Mab anti-ATM Protein Kinase pS1981(clone 10H11.E12).  A 370 kDa band corresponding to phosphorylated ATM is detected (arrowhead, lane 2). The lysate was prepared with HALT phosphatase inhibitor (Pierce).   Pre-incubation of peptide with 50 µg of immunizing phospho peptide negates specific staining (lane 1).  Approximately 30 µg of lysate was added to each lane of an SDS-PAGE gel under non-reducing conditions.  The protein was transferred to nitrocellulose using standard methods.  After blocking the membrane was probed with the primary antibody diluted 1:500 overnight at 4°C followed by washes and reaction with a 1:10,000 dilution of IRDye™800 conjugated Gt-a-Mouse IgG [H&L] (code 610-132-121) for 40 min at room temperature.  LICOR's Odyssey® Infrared Imaging System was used to scan and process the image.  Other detection systems will yield similar results.

ATM phospho S1981 Biotin Conjugated Antibody Description

Background
ATM, the gene mutated in the hereditary disease ataxia-telangiectasia, codes for a protein kinase that acts as a master regulator of cellular responses to DNA double-strand breaks. ATM is normally inactive and the question of how it is activated in the event of DNA damage (due to ionizing radiation for instance) is central to understanding its function. ATM protein is now shown to be present in undamaged cells as an inactive dimer. Low doses of ionizing radiation, which induce only a few DNA breaks, activate at least half of the total ATM protein present, possibly in response to changes in chromatin structure.  The ATM gene encodes a 370-kDa protein that belongs to the phosphoinositide 3-kinase (PI(3)K) superfamily, but which phosphorylates proteins rather than lipids. The 350-amino-acid kinase domain at the carboxy terminus of this large protein is the only segment of ATM with an assigned function. Exposure of cells to IR triggers ATM kinase activity, and this function is required for arrests in G1, S and G2 phases of the cell cycle. Several substrates of the ATM kinase participate in these IR-induced cell-cycle arrests. These include p53, Mdm2 and Chk2 in the G1 checkpoint; Nbs1,
Immunogen
This antibody was produced from a synthetic peptide S-L-A-F-E-E-G-Sp-Q-S-T-T-I-S-S corresponding to aa 1974-1988 of human ATM.
Immunogen Type
Peptide
Post Translational Modification
Phosphorylation
Storage Condition
Store vial at 4° C prior to restoration.   For extended storage aliquot contents and freeze at -20° C or below.  Avoid cycles of freezing and thawing.  Centrifuge product if not completely clear after standing at room temperature.  This product is stable for several weeks at 4° C as an undiluted liquid.  Dilute only prior to immediate use. 
Application Note
This antibody was tested by ELISA and western blotting against both the native and recombinant forms of the protein. This reagent may also be suitable other biotin-streptavidin based assays.
Purity/Specifity
This Protein A Purified Mab antibody is directed against human ATM and is useful in determining its presence in various assays. This monoclonal anti-ATM antibody recognizes the phosphorylated epitope in native and over-expressed proteins found in various tissues and extracts. Reactivity is observed against human and mouse ATM. Cross reactivity with ATM from other mammalian sources has not been tested.
