Wittwer, Carl T. | Influence of PCR reagents on DNA polymerase extension rates measured on real-time PCR instruments | BACKGROUND: Radioactive DNA polymerase activity methods are cumbersome and do not provide initial extension rates. A simple extension rate assay would enable study of basic assumptions about PCR and define the limits of rapid PCR. METHODS: A continuous assay that monitors DNA polymerase extension us... | | 2014-01-01 |

Dwight, Zachary Lawrence | Heterozygote PCR product melting curve prediction | Melting curve prediction of PCR products is limited to perfectly complementary strands. Multiple domains are calculated by recursive nearest-neighbor thermodynamics. However, the melting curve of an amplicon containing a heterozygous single nucleotide variant (SNV) after PCR is the composite of four... | | 2014-01-01 |

Margraf, Rebecca L.; Mao, Rong; Highsmith, W. Edward; Holtegaard, Leonard; Wittwer, Carl T. | Masking selected sequence variation by incorporating mismatches into melting analysis probes | Hybridization probe melting analysis can be complicated by the presence of sequence variations (benign polymorphisms or other mutations) near the targeted mutation.
