Patents by Inventor RYAN O. EMERSON

RYAN O. EMERSON 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).

  • Patent number: 9371558
    Abstract: Compositions and methods are described for standardizing the DNA amplification efficiencies of a highly heterogeneous set of oligonucleotide primers as may typically be used to amplify a heterogeneous set of DNA templates that contains rearranged lymphoid cell DNA encoding T cell receptors (TCR) or immunoglobulins (IG). The presently disclosed embodiments are useful to overcome undesirable bias in the utilization of a subset of amplification primers, which leads to imprecision in multiplexed high throughput sequencing of amplification products to quantify unique TCR or Ig encoding genomes in a sample. Provided is a composition comprising a diverse plurality of template oligonucleotides in substantially equimolar amounts, for use as a calibration standard for amplification primer sets. Also provided are methods for identifying and correcting biased primer efficiency during amplification.
    Type: Grant
    Filed: January 9, 2015
    Date of Patent: June 21, 2016
    Assignee: Adaptive Biotechnologies Corp.

The presently disclosed embodiments are useful to overcome undesirable bias in the utilization of a subset of amplification primers, which leads to imprecision in multiplexed N high throughput sequencing of amplification products to quantify unique TCR or Ig encoding genomes in a sample. Provided is a composition comprising a diverse plurality of template oligonucleotides in substantially equimolar amounts, for use as a calibration standard for amplification primer sets. Also provided are methods for identifying and correcting biased primer efficiency during amplification.
