Patent number: 9096893Abstract: The present invention provides systems, methods and kits for performing a detection assay (e.g., invasive cleavage assay) in combination with an amplification assay (e.g., PCR), where the detection assay employs enzyme footprint probes with relatively short (e.g., 6-12 bases) analyte-specific regions configured to provide a preferred footprint length of duplex for use with a particular nucleic acid modifying enzyme. In some embodiments, such assays are used for target quantification, and in other embodiments, such assays are used for genotyping. In certain embodiments, the use of such short probes allows for assays with increased dynamic range.Type: GrantFiled: July 12, 2013Date of Patent: August 4, 2015Assignee: HOLOGIC, INC.Inventors: Hatim T. Allawi, Victor I. Lyamichev

Patent number: 8288093Abstract: The present invention relates to means for the detection and characterization of nucleic acid sequences, as well as variations in nucleic acid sequences. The present invention also relates to methods for forming a nucleic acid cleavage structure on a target sequence and cleaving the nucleic acid cleavage structure in a site-specific manner. The structure-specific nuclease activity of a variety of enzymes is used to cleave the target-dependent cleavage structure, thereby indicating the presence of specific nucleic acid sequences or specific variations thereof. The present invention further relates to methods and devices for the separation of nucleic acid molecules based on charge. The present invention also provides methods for the detection of non-target cleavage products via the formation of a complete and activated protein binding region. The invention further provides sensitive and specific methods for the detection of human cytomegalovirus nucleic acid in a sample.Type: GrantFiled: April 8, 2008Date of Patent: October 16, 2012Assignee: Third Wave Technologies, Inc.Inventors: Jeff G. Hall, Victor I. Lyamichev, Andrea L. Mast, Mary Ann D. Brow
