  • Publication number: 20150132751
    Abstract: Methods for the detection of the presence or absence of a single nucleotide polymorphism (SNP) in a target nucleic acid in a biological or non-biological sample are described. The methods can include performing an amplifying step using primers, a hybridizing step utilizing a melting probe, and a detecting step, wherein a decreasing shift in the predefined melting temperature of the melting probe is indicative of the presence of the SNP in the sample and wherein the absence of a decreasing shift in the predefined melting temperature of the melting probe is indicative of the absence of the SNP in the sample.

  • Publication number: 20120070831
    Abstract: The invention is a method of amplifying nucleic acids by synthesizing an engineered amplicon containing the sequence of interest, but omitting intervening sequences present in the template molecule. The method utilizes an “amplicon bridge” incorporated into the amplification primers. The length and content of the desired amplicon can be chosen by the operator and can contain unique regions for probe binding.
