  • Publication number: 20120264632
    Abstract: The claimed invention provides for new sample preparation methods enabling direct sequencing of PCR products using pyrophosphate sequencing techniques. The PCR products may be specific regions of a genome. The techniques provided in this disclosure allows for SNP (single nucleotide polymorphism) detection, classification, and assessment of individual allelic polymorphisms in one individual or a population of individuals. The results may be used for diagnostic and treatment of patients as well as assessment of viral and bacterial population identification.

  • Publication number: 20020061526
    Abstract: Disclosed is a method in which DNA sequences derived from polysome-associated mRNA sequences in a mixed sample or in an arrayed single sequence clone can be determined and classified without sequencing. The methods make use of information on the presence of carefully chosen target subsequences, typically of length from 4 to 8 base pairs, and preferably the length between target subsequences in a sample DNA sequence together with DNA sequence databases containing lists of sequences likely to be present in the sample to determine a sample sequence. The preferred method uses restriction endonucleases to recognize target subsequences and cut the sample sequence. Then carefully chosen recognition moieties are ligated to the cut fragments, the fragments amplified, and the experimental observation made. Polymerase chain reaction (PCR) is the preferred method of amplification.
