ATM phospho Ser1981 antibody (Clone 10H11.E.12) tested by immunofluorescence.
HeLa cells stained with ATM phospho Ser1981 antibody (Clone 10H11.E.12) at a 1:500 dilution using using MAX Stain™ Immunofluorescence Tools.
Panel A: Normal HeLa cells.
Panel B: HeLa cells treated with 3 Gy ionizing radiation and collected 30 minutes post-exposure.
Top images: Cells stained with DAPI.
Middle images: Same cells stained with ATM phospho Ser1981 mAb (Clone 10H11.E.12).
Bottom images: Merge of the two images above.
Note the Panel B-middle image, which shows intense nuclear clustering of ionizing radiation-induced phosphorylation of ATM at serine 1981. In contrast, Panel A-middle image shows no detectable phosphorylated ATM.

for ATM phospho Ser1981 antibody (mAb) (Clone 10H11.E.12)Background

ATMAtaxia Telangiectasia Mutated is a PI3-family protein kinase and a critical cell cycle checkpoint protein. ATM and a related protein, ATR, play crucial roles in the maintenance of genome integrity and the response to DNA damage. Upon activation, ATM phosphorylates itself at serine 1981 and then phosphorylates a number of downstream proteins (e.g. BRCA1, CHK2, H2AX, p53, NBS1, SMC1) resulting in cell cycle arrest and the initiation of DNA damage repair. Loss of function of ATM is causal to a variety of syndromes involving increased incidence of several cancers.

for ATM phospho Ser1981 antibody (mAb) (Clone 10H11.E.12)Storage

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
