Figure Lengend Snippet: Fig. 1. Average total fold intensity of phospho-protein signal as compared to median control value. Colored bars (dark blue = 0.5 Gy, light blue = 0.1 Gy and green = 0.05 Gy) indicate values significantly different from controls (yellow). Significance bars are shown for all significant differences between doses and 0 (p ≤0.05). Average fold intensity levels are shown at 2 h post radiation for γH2AX (A), pATF2 (B) and pSMC1 (C). Persistent effects are shown at 24 h for γH2AX (D), pATF2 (E) and pSMC1 (F).

Article Snippet: For staining, 0.5 × 106 fixed cells were washed in phosphate buffered saline (PBS), resuspended in blocking buffer (2% FBS/PBS) and incubated for 1 h with primary antibody on ice, with resuspension of the pellet every 15 min. Primary antibodies used in flow cytometry include mouse monoclonal γH2AXSer139 (1:800 dilution) and pSMC1Ser957 (1:800 dilution) from Millipore (Temecula, CA) and rabbit polyclonal pATF2 Ser490/498 (1:1000 dilution) from Rockland, Inc. (Gilbertsville, PA).

Figure Lengend Snippet: Fig. 6. Average total fold intensity of pATF2 signal intensity divided by fluence and graphed versus LET. Average fold intensity levels are shown at 2 h post radiation for 0.05 Gy (A), 0.1 Gy (B) and 0.5 Gy (C). Persistent effects are shown at 24 h for 0.05 Gy (D), 0.1 Gy (E) and 0.5 Gy (F).
