Abstract (en)

[origin: WO9907899A1] The present invention is directed to improved methods for detection of mutations in DNA using Denaturing Matched Ion Polynucleotide Chromatography (DMIPC). The invention includes the following aspects: analysis of PCR amplification products to identify factors that affect PCR replication fidelity; design of PCR primers; selection of an optimal temperature for performing DMIPC; selection of the mobile phase composition for gradient elution; methods for column preparation and maintenance; and methods for preparing polynucleotide samples prior to chromatographic analysis.
