  HeLa cells were fixed in 4% paraformaldehyde for 10 minutes and permeabilized in 0.5% Triton X-100 in PBS for 5 minutes. The cells were incubated with 53BP1 Antibody conjugated to DyLight 550 (TA309918R) at 5 ug/ml for 1 hour at room temperature. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 40X objective.

Immunofluorescent images were obtained by confocal microscopy. White bar = 20 microns. A) DMSO alone, B) ENZ alone, C) 1 Gy, D) ENZ + 1 Gy. White bar = 20 microns.

• An intracellular stain was performed on RH-30 cells with 53BP1 Antibody (Catalog #TA309918AF647) (blue) and a matched isotype control (orange). Cells were fixed with 4% PFA and then permeabilized with 0.1% saponin. Cells were incubated in an antibody dilution of 5 ug/mL for 30 minutes at room temperature. Both antibodies were conjugated to Alexa Fluor 647.

Cells were fixed with 4% PFA and then permeabilized with 0.1% saponin. Cells were incubated in an antibody dilution of 2.5 ug/mL for 30 minutes at room temperature. Both antibodies were conjugated to Alexa Fluor 647.

• HeLa cells were fixed in 4% paraformaldehyde for 10 minutes and permeabilized in 0.5% Triton X-100 in PBS for 5 minutes. The cells were incubated with 53PB1 Antibody conjugated to DyLight 550 (TA309918R) at 5 ug/ml for 1 hour at room temperature. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 100X objective and digitally deconvolved.

• HPV+ HNSCCs have decreased expression of NHEJ and HR proteins including DNA-Pk and BRCA2Cells were treated with mock or 4 Gy radiation, harvested and lysed at 15 minutes post-treatment, and analyzed by western blot for relative expression of indicated proteins. β-actin was used as a loading control. Shown is a representative blot from 2 independent experiments.

• Total protein from HeLa, A431, Neuro2A, and PC12 was separated on a 12% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 1.0 ug/mL in 5% block buffer and detected with an anti-rabbit HRP secondary antibody using chemiluminescence. The observed molecular weight for these samples are ~250 kDa and the theoretical molecular weight is 214 kDa.

• An intracellular stain was performed on Ntera2 cells with 53BP1 Antibody TA309918 (blue) and a matched isotype control NBP2-24891 (orange). Cells were fixed with 4% PFA and then permeabilized with 0.1% saponin. Cells were incubated in an antibody dilution of 1.0 ug/mL for 30 minutes at room temperature, followed by Rabbit IgG (H+L) Cross-Adsorbed Secondary Antibody, Dylight 550 (SA5-10033, Thermo Fisher).

• 53BP1 was detected in immersion fixed HeLa cells (left) but was not detected in 53BP1 knockout Hela cells (right) using Rabbit Anti-human 53BP1 polyclonal antibody (Catalog #TA309918) at 0.3 ug/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; Catalog # NL004) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

• Depletion of PNUTS and NPAT induces a global DDR.(A) Induction of telomere dysfunction–induced foci (TIF) upon candidate knockdown in HeLa cells from Fig 5. Depletion of TRF2 was used as a positive control. 53BP1 was detected by indirect IF and telomeres by FISH with a Cy3-[CCCTAA]3 probe. (B) Frequency distribution of the number of TIFs per cell from (A). n indicates the number of cells analyzed for each condition and red lines mark the mean.

• NIH3T3 cells were fixed in 4% paraformaldehyde for 10 minutes and permeabilized in 0.5% Triton X-100 in PBS for 5 minutes. The cells were incubated with anti-53BP1 Antibody TA309918 at 2 ug/ml overnight at 4C and detected with an anti-rabbit Dylight 488 (Green) at a 1:1000 dilution for 60 minutes. Alpha tubulin (DM1A) NB100-690 was used as a co-stain at a 1:1000 dilution and detected with an anti-mouse Dylight 550 (Red) at a 1:1000 dilution. Nuclei were counterstained with DAPI (Blue).
