Patents by Inventor Luis Ugozzoli

Luis Ugozzoli 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: 8357672
    Abstract: RNA is extracted from cellular material with a reagent that includes heparin, a reducing agent to reduce disulfide bonds, a chelating agent, a buffer, and an alkali metal halide. The reagent does not require the use of organic solvents, and the reagent allows extraction to be performed in a relatively short period of time in comparison to the prior art.
    Type: Grant
    Filed: June 5, 2009
    Date of Patent: January 22, 2013
    Assignee: Bio-Rad Laboratories, Inc.
    Inventors: Camille M. Diges, Luis Ugozzoli

  • Publication number: 20080003585
    Abstract: Purification of either DNA or RNA and amplification through PCR or reverse-transcriptase PCR are performed in a common microfluidics device by the inclusion of diatomaceous earth in a reservoir within the device and by the use of microfluidics technology for conveying fluids through the reservoir and through microchannels within the device.

  • Publication number: 20070207483
    Abstract: The present invention provides methods and kits using low conductivity buffers for the detection of mRNA from a cell lysate separated in a microfluidic device. The buffers do not affect the integrity of the cell nucleus, thereby allowing for generation of a cell lysate that can be directly used as a template in reverse transcriptase (RT)-polymerase chain reaction (PCR) amplification reactions without contaminating genomic DNA.

    Date of Patent: May 28, 1996
    Assignee: City of Hope
    Inventors: R. Bruce Wallace, Luis Ugozzoli
  • Patent number: 5508179
    Abstract: This invention provides methods and compounds relating to the use of deoxyribose nicotinamide adenine dinucleotide (dNAD.sup.+) analogues in NAD.sup.+ -dependent ligation reactions. The compounds and methods may be used in NAD.sup.+ -dependent ligation reactions generally, and to increase the specificity of NAD.sup.+ -dependent ligation reactions.
