SNP allelic discrimination plot for SNP at position 28 in the erm(41) gene. This is a representative figure of allelic discrimination between probes Allele C and Allele T with isolate CI20-43 with C28 shown in the upper quadrant of the y axis. The isolates with T28 are located in the far right quadrant along the x axis: CI6-3, CI20-19, CI20-25, CI20-30, CI20-31, CI20-35, CI20-36, CI20-37, CI20-38, CI20-42, CI20-44, and M. abscessus ATCC 19977T . The negative control with water instead of genomic DNA is located in the left lower quadrant of the graph close to zero.
