Patent number: 11859238Abstract: Improved methods for use in nucleic acid amplification, including multiplex amplification, where the amplification is carried out in two or more distinct phases are disclosed. The first phase amplification reaction preferably lacks one or more components required for exponential amplification. The lacking component is subsequently provided in a second, third or further phase(s) of amplification, resulting in a rapid exponential amplification reaction. The multiphase protocol results in faster and more sensitive detection and lower variability at low analyte concentrations. Compositions for carrying out the claimed methods are also disclosed.Type: GrantFiled: January 7, 2019Date of Patent: January 2, 2024Assignee: GEN-PROBE INCORPORATEDInventors: Norman C. Nelson, Lyle J. Arnold, Jr., Lizhong Dai, Steven Phelps, Jijumon Chelliserry

Patent number: 11840716Abstract: Disclosed are methods for amplifying a nucleic acid target region using an amplification oligomer comprising a target-binding segment and a heterologous displacer tag situated 5? to the target-binding segment. Initiation of an amplification reaction from the tagged amplification oligomer produces an amplicon comprising the displacer tag, such that once the complement of the displacer tag has been incorporated into a second amplicon, a displacer oligonucleotide having a sequence substantially corresponding to the displacer tag sequence is used to participate in subsequent rounds of amplification for displacement of an extension product primed from a site within the second amplicon 5? to the displacer priming site. Also disclosed are related kits and reaction mixtures comprising the displacer-tagged amplification oligomer and corresponding displacer oligonucleotide.Type: GrantFiled: December 28, 2020Date of Patent: December 12, 2023Assignee: GEN-PROBE INCORPORATEDInventors: Norman C.

Patent number: 11235295Abstract: A method of processing a sample in a receptacle comprising a plurality of chambers. Each of the chambers is connected to at least one other chamber by a portal and at least a first one of the chambers is formed of a flexible material. The method includes the steps of causing gas bubbles contained in the first chamber to accumulate in a portion of the first chamber, applying a compressive external force to the first chamber to cause some or all of the liquid contents of the first chamber to flow into an interconnected second chamber through a portal connecting the first and second chambers; and preventing the gas bubbles accumulated in a portion of the first chamber from flowing through the portal into the second chamber.Type: GrantFiled: December 27, 2018Date of Patent: February 1, 2022Assignees: GEN-PROBE INCORPORATED, QUALIGEN, INC.Inventors: Scott S.

Patent number: 10744469Abstract: A receptacle having a plurality of interconnected chambers arranged to permit multiple process steps or processes to be performed independently or simultaneously. The receptacles are manufactured to separate liquid from dried reagents and to maintain the stability of the dried reagents. An immiscible liquid, such as an oil, is included to control loading of process materials, facilitate mixing and reconstitution of dried reagents, limit evaporation, control heating of reaction materials, concentrate solid support materials to prevent clogging of fluid connections, provide minimum volumes for fluid transfers, and to prevent process materials from sticking to chamber surfaces. The receptacles can be adapted for use in systems having a processing instrument that includes an actuator system for selectively moving fluid substances between chambers and a detector. The actuator system can be arranged to concentrate an analyte present in a sample.Type: GrantFiled: December 12, 2008Date of Patent: August 18, 2020Assignees: Gen-Probe Incorporated, Qualigen, Inc.Inventors: Scott S.

Patent number: 10724085Abstract: Compositions, reaction mixtures, and methods for performing an amplification reaction, including multiplex amplification reaction, wherein the method comprises using one or more amplification oligomer complexes comprising linked first and second amplification oligomer members. In one aspect, the amplification oligomer complex is hybridized to a target nucleic acid, the target nucleic acid with hybridized amplification oligomer complex is then captured, and other components are washed away. Target sequences of the target nucleic acids are pre-amplified to generate a first amplification product. The first amplification product is amplified in one or more secondary amplification reactions to generate second amplification products.Type: GrantFiled: February 22, 2018Date of Patent: July 28, 2020Inventors: Steven T. Brentano, Dmitry Lyakhov, Norman C. Nelson, James D. Carlson, Michael M. Becker, Lyle J. Arnold, Jr.
