Experimental details: Immunofluorescence analysis of TP53-binding protein 1 was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with 53BP1 Polyclonal Antibody (Product # PA1-16566) at 1:100 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32790), (1:2000), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing Nuclear localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

Experimental details: Flow cytometry of 53BP1 in Ntera2 cells (blue) and a matched isotype control (orange). Samples were incubated in 53BP1 polyclonal antibody (Product # PA1-16566) using a dilution of 1.0 µg/mL for 30 minutes at room temperature followed by a Rabbit IgG (H+L) Cross-Adsorbed Secondary Antibody, Dylight™ 550 (Product # SA5-10033). Cells were fixed with 4% PFA and then permeabilized with 0.1% saponin.

Experimental details: Flow cytometry of 53BP1 in HeLa cells (blue) and a matched isotype control (orange). Samples were incubated in 53BP1 polyclonal antibody (Product # PA1-16566) using a dilution of 5 µg/mL for 30 minutes at room temperature. Cells were fixed with 4% PFA and then permeabilized with 0.1% saponin. Both antibodies were conjugated to Alexa Fluor 488.

Experimental details: Figure 6 Assessing 53BP1 foci and cell death in intestinal sections after gamma and 56 Fe radiation exposure. A) Intestinal sections from 6 to 8 week control, 1-year post-exposure control, 2 Gy gamma, and 1.6 Gy 56 Fe 1-year post-exposure mice were immunofluorescently stained for 53BP1. B) Quantification of 53BP1 foci in intestinal cell nuclei counterstained with DAPI. C) Quantification of TUNEL staining of intestinal sections after exposure to gamma and 56 Fe radiation. *significant compared to 6-8 wks unirradiated control; **significant compared to 1-year post-exposure unirradiated control; ***significant compared to gamma radiation.
