  • Sample preparation for flow cytometry
    Patent number: 9933341
    Abstract: Described herein are methods and reagents for identifying and analyzing at least one microorganism (e.g. bacteria) in a sample and reducing the background signal intensity obtained when analyzing the sample by flow cytometry. The sample is prepared by combining the sample with a background signal-reducing molecule or with a nucleic acid stain covalently linked to a quencher. A portion of the particulate matter in the sample can optionally be removed with a resin prior to staining with a nucleic acid stain.
    Type: Grant
    Filed: April 4, 2013
    Date of Patent: April 3, 2018
    Assignee: Becton, Dickinson and Company
    Inventors: Xiao Li, Yongqiang Zhang, Kenneth Anthony Kopher, John D. Mantlo, William Alfred Pope, Song Shi, Axel A. Yup
  • Method for improving analysis of microorganisms in complex matrices
    Patent number: 9645057
    Abstract: A process for determining one of the presence, absence, or total of microorganisms (e.g. bacteria) in a sample. According to the process, a biological sample containing complex matrices is obtained. The sample is first combined with a resin to adsorb complex matrices from the sample. The resin is removed from the biological sample. The sample so prepared is then analyzed by flow cytometry.
