Abstract The ability of fluorescence resonance energy transfer, molecular-beacon, and TaqMan probes to detect single nucleotide polymorphism (SNP) in the presence of a wild-type allele was evaluated using drug resistance-conferring SNPs in mixed Mycobacterium tuberculosis DNA. It was found that both the absolute quantity and the ratio of alleles determine the detection sensitivity of the probe systems
