Patents by Inventor Renee Howell

Renee Howell 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).

  • Publication number: 20200264055
    Abstract: The present invention relates to the use of one or more amplicons as temperature calibrators. In some embodiments, the calibrators may be used to calibrate the temperature of a microfluidic channel in which amplification and/or melt analysis is performed. In some embodiments, the amplicons may be genomic, ultra conserved elements and/or synthetic. The amplicon(s) may have a known or expected melt temperature(s). The calibrators may be added to primers of study or may follow or lead the primers of study in the channel. The amplicon(s) may be amplified and melted, and the temperature(s) at which the amplicon(s) melted may be determined. The measured temperature(s) may be compared to the known temperature(s) at which the amplicon(s) was expected to melt. The difference(s) between the measured and expected temperatures may be used to calibrate/adjust one or more temperature control elements used to control and/or detect the temperature of the channel.

  • Publication number: 20170009279
    Abstract: The present invention relates to methods, kits, probes, and systems for distinguishing between nucleotide variants that are close in proximity on a gene. The methods, kits, probes, and systems can include the use of a small amplicon assay in combination with two unlabeled probes in a high resolution thermal melting analysis of a biological sample containing a locus of interest in order to discern between disease-causing and benign variants that are close in proximity on a gene within the biological sample. The present invention also relates to method of detecting a disease in a patient based on the patient's genotype by determining whether the patient has a disease-causing variant at a locus of interest. The signature melt curves produced by the unlabeled probe tests can be analyzed using HRMA software to distinguish between disease-causing and benign variants that are close in proximity on a gene within the biological sample.
