Comparisons of the protein ratio obtained from western blots and SILAC-MS analysis

Protein name	Normalized ratio of western blot		Mean ASAP ratio of SILAC
	15 h/Ctrl	48 h/Ctrl	15 h/Ctrl	48 h/Ctrl
XRCC5	0.80 ± 0.21	0.68 ± 0.18	0.86 ± 0.24	0.49 ± 0.25
XRCC6	0.71 ± 0.19	0.66 ± 0.04	0.64 ± 0.54	0.77 ± 0.11

Gray intensity analysis for western blot was measured with Photoshop CS. The value was then normalized using the levels of β-actin. Average normalized value was presented from three independent experiments. MS = mass spectrum.
