  • Patent number: 9023295
    Abstract: An adapter for use with a hand-held electronic device for use in detecting the optical properties of a sample. The adapter includes a backing plate having an integral surface that secures the adapter to the electronic device. The adapter also includes a sample housing having a sample holder and a cap. The sample holder is configured to receive the placement of a sample and/or a sample vessel. The backing plate includes an orifice that allows the passage of light from the sample to the detector of the electronic device. The backing plate may also include another orifice that allows for light emitted from an emitter of the electronic device to enter into the sample holder. The sample holder may also include reflective surfaces that direct light to/from the sample as well as filters that filter the wavelength of light sent to sample and/or detected by the detector.

  • Patent number: 8288147
    Abstract: Methods for synthesizing isopentenyl pyrophosphate are provided. A first method comprises introducing into a host microorganism a plurality of heterologous nucleic acid sequences, each coding for a different enzyme in the mevalonate pathway for producing isopentenyl pyrophosphate. A related method comprises introducing into a host microorganism an intermediate in the mevalonate pathway and at least one heterologous nucleic acid sequence, each sequence coding for an enzyme in the mevalonate pathway necessary for converting the intermediate into isopentenyl pyrophosphate. The invention also provides nucleic acid sequences, enzymes, expression vectors, and transformed host cells for carrying out the methods.

  • Patent number: 7927794
    Abstract: The present invention provides isolated, genetically modified host cells, where a host cell is genetically modified with a nucleic acid that includes a nucleotide sequence encoding a biosynthetic pathway enzyme. Synthesis of the enzyme in the host cell results in conversion of a substrate for the enzyme into a biosynthetic pathway intermediate, which intermediate is produced in an amount effective to inhibit growth of the genetically modified host cell. The present invention further provides compositions and kits comprising a subject genetically modified host cell. Subject host cells are useful for identifying a gene product having activity in a biosynthetic pathway. The present invention further provides methods of identifying a gene product having activity in a biosynthetic pathway.
