Fig. 1From: Detection of EGFR mutation of pulmonary adenocarcinoma in sputum using droplet digital PCRDroplet digital PCR data analysis. a 1-D plot with each droplet from a sample plotted on the graph of fluorescence intensity versus droplet number is shown. Blue dots denote EGFR mutant droplets and gray dots denote wild-type EGFR droplets. a Ex21 in sputum sample (Case1), b positive control for Ex21, c Ex19 in sputum sample (Case7), and d positive control for Ex19Back to article page
