Patent number: 8691508Abstract: Contemplated systems and methods allow analysis of multiple and distinct patient samples using a labeling scheme that entirely avoids carry-over of a label or reagent to the analytic platform, typically an addressable solid phase. In preferred aspects, a hybridization portion, a fluorophore, and/or a quencher are removed by a 5?-3?-exonuclease activity of a polymerase from a reporter oligonucleotide to so remove the oligonucleotide from the pool of molecules that bind to the solid phase and/or or to provide signal differentiation by removal of a fluorophore or quencher.Type: GrantFiled: December 13, 2007Date of Patent: April 8, 2014Assignee: Autogenomics, Inc.Inventor: Nanibhushan Dattagupta

Publication number: 20110086771Abstract: Improved biochips comprise a matrix layer coupled to a substrate, wherein the matrix layer includes a plurality of ligands in a plurality of predetermined positions and wherein ligands bind to an anti-ligand disposed in a sample fluid. Preferred matrix layers are multi-functional matrix layers that reduce autofluorescence, incident-light-absorption, charge-effects, and/or surface unevenness of the substrate, and contemplated biochips may comprise additional matrix layers. Contemplated biochips may be useful in detection and/or quantification of various anti-ligands, including polypeptides, polynucleotides, carbohydrates, pharmacologically active molecules, bacterial or eukaryotic cells, and/or viruses.Type: ApplicationFiled: August 27, 2010Publication date: April 14, 2011Applicant: AUTOGENOMICS, INC.Inventors: Vijay Mahant, Fareed Kureshy

Publication number: 20110046001Abstract: A method of detecting the presence of a plurality of respiratory viruses using a multiplexed diagnostic assay is disclosed. The method provides a plurality of oligonucleotides that each is specific for a specific respiratory virus. A multiplex PCR is run using the oligonucleotides, which produces double-stranded products. The method also provides a plurality of extension oligonucleotides that each is specific for a specific double-stranded product. Each extension oligonucleotide also has a distinct second portion having a unique sequence. A primer extension reaction is run using the extension oligonucleotides, which produces single-stranded products. The single-stranded products are hybridized to a solid carrier.Type: ApplicationFiled: November 20, 2008Publication date: February 24, 2011Applicant: AUTOGENOMICS, INC.Inventors: Jacques Corbeil, Fredric Raymond, Guy Boivin

Publication number: 20080311568Abstract: Contemplated methods and kits include a plurality of single stranded oligonucleotides that comprise a discriminating sequence that is encompassed on one end by a label and on the other end by a unique tag sequence. In one preferred aspect, the discriminating sequence is an RNA repeat unit, forms a heteroduplex with a complementary DNA repeat unit of the target nucleic acid, and the discriminating agent is RNaseH. Using such systems, the number of repeat units can be simply identified by hydrolysis of the discriminating sequence where such sequence is adjacent to a predetermined number of DNA repeat units in the single stranded oligonucleotide.Type: ApplicationFiled: December 12, 2005Publication date: December 18, 2008Applicant: AUTOGENOMICS, INC.Inventors: Phillip Kim, Vijay Mahant
