Patents by Inventor Cindy R. WalkerPeach

Cindy R. WalkerPeach has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for monitoring nucleic acid assays using synthetic internal controls with reversed nucleotide sequences
    Publication number: 20030077622
    Abstract: The present invention relates to methods and compositions that provide a positive control to identify inhibition during a signal amplification reaction. The methods and compositions of the present invention are designed to run in the same tube or assay environment as the experimental or target sample and contain a copy of the target sequence in an inverted form.
    Type: Application

  • Compositions, methods and kits for allele discrimination
    Publication number: 20020037507
    Abstract: The invention relates to sequence-specific polynucleotide probes, pairs of probes, the design of pairs of probes in relation to the strands of target nucleic acid, and coordinate sequence-specific pairs of polynucleotide primers, and also relates to kits containing such probes, probe pairs, primers, and primer pairs. The invention thus relates to kits and methods employing such polynucleotides. The invention relates to six specific allele discrimination kits. The specific kits are developed for the detection of four single base substitutions in the human CCR2, SDF1, Factor V, MTHFR, Factor XIII genes, and a 32-bp deletion in the human CCR5 gene. The capability of using two allele-specific molecular beacons in the same PCR solution enables the simultaneous determination of three possible allelic representations of a given sequence change in target DNA (Allele 1/Allele 1, Allele 2/Allele 2, Allele 1/Allele 2).
