Western blot was performed as described previously (19 (link), 20 (link)), using pATM (Ser1981) (D6H9), MRE11, RAD50, NBS1, PARP-1, pAKT pCHK2 (Thr68) (C13C1), γH2AX (Cell Signaling, Danvers, MA), and β-Actin (8H10D10) antibodies (Cell Signaling). Appropriate horseradish peroxide-conjugated secondary antibodies (Cell Signaling) were used, and proteins were detected with the Amersham ECL Prime Western Blotting Detection Reagent (GE Healthcare Bio-Sciences, Pittsburgh, PA). The blotted membranes were stripped and re-probed with ATM (D2E2), AKT, and CHK2 (D9C6) antibodies (Cell Signaling). Protein bands were captured and quantified by Chemi DocTM MP Imaging System (Bio-Rad).
