Abstract
A method for analysing genetic mutations, and in particular single nucleotide polymorphisms (SNPs) and/or somatic mutations, is described, as well as methods for preferentially amplifying one allelic form compared with another form. The methods use an oligonucleotide probe which hybridises to a first allele with a lower melting temperature (Tm) than that with which it hybridises to a second allele, together with amplification primers which flank the oligonucleotide probe binding site and which bind to the sample with a higher Tm than that of the probe and the first allele. An amplification reaction may be carried out at a temperature such that the probe is preferentially hybridised to the second allele, thereby amplifying the first allele. The amplified sequences may be detected using the same probe as acted as the blocking probe during amplification.
