Discriminating Highly Similar Transcripts Using rhPCR

Description of RNase H-dependent PCR, a technology developed to increase PCR specificity and eliminate unwanted interactions between primer sets (e.g., primer-dimers, etc.). An example is provided in which it is used to distinguishing highly similar alternatively spliced sequences. This technology can also be useful in genotyping applications, in highly multiplexed qPCR assays, library construction for Next Generation DNA Sequencing, and for rare allele detection, where the added specificity provided by the blocked-cleavable primers enables detection of a rare mutant allele in a background of large amounts of wild type DNA.
