Fig. 1From: Development of a multiplex droplet digital PCR method for detection and monitoring of Mycobacterium tuberculosis and drug-resistant tuberculosisThe sample mix undergoes droplet formation so that the DNA strands are compartmentalized into separate droplets. Then, they are amplified via PCR, and the amplified product reacts with the fluorescence-labeled probe. Each droplet is scanned and plotted in its corresponding coordinates. The x-axis represents signal detected from Channel 2 (VIC/HEX), while the y-axis represents signal detected from Channel 1 (FAM)Back to article page
