  • METHODS AND APPARATUS FOR SEQUENTIAL AMPLIFICATION REACTIONS
    Publication number: 20210285025
    Abstract: The invention provides methods and apparatus for carrying out multiple amplification reactions in a single reaction chamber by successive cycles of loading reaction mixture, amplifying, and removing spent reaction mixture in a fluidly closed reaction system. In particular, the present invention allows amplification of a plurality of target polynucleotides from a single sample by carrying out under closed-loop control successive amplifications of different target polynucleotides from different portions of the sample.
    Type: Application
    Filed: December 22, 2020
    Publication date: September 16, 2021
    Inventors: Joseph H. Smith, David H. Persing, Alan Wortman, Ronald Chang, David Swenson
