Supplementary Fig. 1 Bar plots represent events number for ddPCR reactions using
(a) 80 ng and (b) 2.5 ng DNA template. Absolute events number was labeled above
the bar. Red arrows indicate too few (a) negative and (b) positive events which result
in ambiguous or inconsistent CN determination. Light blue: DEFB4 positive; Dark
blue: DEFB4 negative; Light green: RPP30 positive; Dark green: RPP30 negative
