  • Multiple amplification cycle detection
    Patent number: 11959132
    Abstract: Methods and devices are provided for simultaneously amplifying a plurality of sample wells for a predetermined amount of amplification, detecting whether amplification has occurred in a first set of the wells, amplifying for an additional amount of amplification and detecting whether amplification has occurred in a second set of the wells. Methods are also provided for analyzing a target nucleic acid sequence using melt curves that were generated in a plurality of amplification cycles.
    Type: Grant
    Filed: May 25, 2021
    Date of Patent: April 16, 2024
    Assignee: BioFire Diagnostics, LLC
    Inventors: Randy P. Rasmussen, Robert John Crisp, Andrew Clinton Hemmert, Elizabeth Barker Campbell, Thomas Charles Robbins, David J. Eyre
