Linearity and sensitivity of Microbial DNA qPCR Arrays.
Linearity and sensitivity for each Microbial DNA qPCR Array was determined using synthetic templates over a 6 log serial dilution ranging from 1 copy to 1 million copies. The following are representative results for all the qPCR assays. [A] shows the real-time amplification curves of the KPC antibiotic resistance gene qPCR assay. In [B], a standard curve was prepared that shows that the primer efficiency equals 103% (calculated from slope = –3.3236) and the correlation coefficient is 0.9983, indicating optimum performance for the KPC qPCR assay. All Microbial DNA qPCR Assays have primer efficiencies between 80–120% and correlation coefficients (R)>0.995.
