Patents by Inventor Patrick Rivers

Patrick Rivers 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: 20210054429
    Abstract: The present disclosure describes methods and systems for improving the expression of a properly folded, biologically active protein of interest in a cell free synthesis system. The methods and systems use a bacterial cell free extract having an active oxidative phosphorylation system, and include an exogenous protein chaperone. The exogenous protein chaperone can be expressed by the bacteria used to prepare the cell free extract. The exogenous protein chaperone can be a protein disulfide isomerase and/or a peptidyl-prolyl cis-trans isomerase. The inventors discovered that the combination of a protein disulfide isomerase and a peptidyl-prolyl cis-trans isomerase produces a synergistic increase in the amount of properly folded, biologically active protein of interest.

  • Publication number: 20190338293
    Abstract: This invention provides high growth capacity strains of auxotrophic Escherichia coli and methods for generating thereof. The high growth capacity strains express a complementing auxotrophic plasmid that allows the strain to grow in the absence of the auxotrophic amino acid. Also, provided herein is a method for preparing a bacterial cell extract of a high growth capacity strain of auxotrophic Escherichia coli for use in an in vitro protein expression.

  • Publication number: 20090208685
    Abstract: The presently disclosed subject matter is directed to packaging films that include semi-crystalline cyclic olefin copolymers, amorphous cyclic olefin copolymers, and/or cyclic olefin polymers present in the sealant layer and/or in the layer adjacent to the sealant layer such that the film exhibits decreased scalping of essential oils, flavor compounds, antibacterial additives, antifungal additives, and the like from products packaged using the disclosed films. More particularly, the presently disclosed films minimally scalp polar cyclic compounds from the packaged product. The presently disclosed subject matter is further directed to making and using the disclosed films.
