A ONE-WELL ASSAY FOR HIGH THROUGHPUT DETECTION OF SINGLE NUCLEOTIDE POLYMORPHISMS |
摘要 |
The present invention relates to a novel one-well assay which couples a conventional polymerase chain reaction (PCR) amplification step to a single nucleotide primer extension step for the the determination of nucleotide sequence variations in the genotyping of single nucleotide polymorphisms and other DNA variations detected by primer extension methods. A PCR amplification step, a phosphatase digestion step (or a molecular weight-selective filter step), and a primer extension step are consecutively performed in the same well plate followed by electrospray mass spectrometry detection of a single nucleotide polymorphism bases. Alternative one-well assays which utilize exonuclease I or lambda -exonuclease in addition to the phosphatase digestion step are also disclosed. |
