  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human lung carcinoma tissue labelling DNA PKcs (phospho S2056) with purified ab124918 at 1/100. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. Goat Anti-Rabbit IgG H&L (HRP) ab97051, a HRP-conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody (1/500). Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.

  ELISA - Anti-DNA PKcs (phospho S2056) antibody [EPR5670] (ab124918)

  Serially diluted ab124918 was bound to immobilised phospho- or control peptides (1 microgram per mL). The antibody was detected by HRP-labelled goat anti-rabbit IgG (Goat Anti-Rabbit IgG H&L (HRP) preadsorbed ab97080; diluted 50000 times) and signal was developed with TMB substrate.

  OI-RD Scanning - Anti-DNA PKcs (phospho S2056) antibody [EPR5670] (ab124918)

  We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody.
  Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

  ChIC/CUT&RUN sequencing - Anti-DNA PKcs (phospho S2056) antibody [EPR5670] (ab124918)

  ChIC/CUT&RUN was performed using a pAG-MNAse at a final concentration of 700 ng/mL, 2.5 x 10^5 U2OS cells treated with Etoposide (10μM 20h) and 5 µg of ab124918 [EPR5670]. The resulting DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 10 million reads. The negative IgG control Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab172730 is also shown.
  
  Additional screenshots of mapped reads can be found in the Protocol booklet in the Support and downloads section.

  The combination of DNA-PK inhibitors and M1 virus-induced enhanced DNA damage response. a Cells were treated with vehicle, NU7441 (1 μM), M1 (MOI = 1) or NU7441/M1 for 36 h, and comet assay was used to assess double-strand breaks (DSBs). b Quantification of tail moment from a. Box-and-whisker plots show the median (horizontal line), interquartile range (box) and min to max of the data. 62, 61, 60 and 64 cells of vehicle, NU7441, M1 and NU7441/M1 groups, were analyzed, ***P < 0.001 by Kruskal–Wallis test. c, d Immunoblots of proteins after infection with M1 virus (MOI = 1) for 0, 24, 36 and 48 h. e, f Cells were exposed to NU7441 (1 μM), M1 (MOI = 1) or a combination as indicated. p-H2AX (a marker of DNA damage response), cleaved-caspase-3 (a marker of apoptosis) and p-DNA-PKcs (target of NU7441) were determined by western blot. g, h Cells were transfected with siRNA targeting DNA-PKcs (48 h), and this was followed by M1 virus infection (MOI = 1) for 48 h. Proteins were examined by western blot
