Daniel Kephart 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: 20140272940
    Abstract: The present disclosure, in some embodiments, relates to compositions and methods for detection of multiple target nucleic acid sequences by a single nucleic acid amplification based assay (e.g. PCR). Compositions comprising two or more primers are described for multiple target nucleic acid detection. Methods for differential detection of microorganisms (including strains/serovars/subtypes thereof) and cell types comprise a single step method to detect a signature of target nucleic acid sequences comprising: two, three or more target nucleic acids that are uniquely present in a microorganism/strain/serovar/subtype and/or cell and absent in other closely related organisms/cells. Embodiments relate to methods of diagnosis of diseases or conditions that can be detected by detecting the presence of two or more nucleic acid target markers.
