Studying the effect of single mismatches in primer and probe binding regions on amplification curves and quantification in real-time PCR.

Comparison of a broad range of characteristics of real-time PCR amplification curves yielded only slight alterations for low numbers of mismatches in the primer binding regions, resulting in a quantification error up to 63.12%. The effects were more pronounced for mismatches in the probe binding region and resulted in a quantification error up to 33%.
