Abstract
Provided are oligonucleotides that are capable of detecting KRAS and PIK3CA mutations in both cancer patients and healthy individuals with high specificity in kPCR assays. When the oligonucleotides are used as forward primers in conjunction with a defined genotyping algorithm spreadsheet, the primers are capable of enhancing detection of KRAS codon 12, 13, and 61 and PIK3CA codon 542, 545, and 1047 single nucleotide polymorphisms (SNPs) in a background of wild-type sequences. The oligonucleotides of the present invention are also capable of preventing pseudogene amplification when the oligonucleotides are hybridized as reverse primers or detection probes to the mismatch sequences.
