Publication number: 20210380967Abstract: This disclosure relates to improved methods of identifying A-to-I RNA edits in a sample. In certain embodiments, this disclosure relates to methods of purifying RNA containing an inosine base comprising the steps of: exposing an RNA sample to endonuclease V or fusion thereof and calcium ions in the absence of magnesium ions providing an RNA and endonuclease V binding complex. In certain embodiments, the methods further comprise purifying the RNA and endonuclease V binding complex from unbound RNA in the sample; separating the RNA from endonuclease V providing separated RNA; sequencing the separated RNA; and identifying positions in the RNA sequences wherein A-to-I edits occur. In certain embodiments, the RNA is derived from a cell.Type: ApplicationFiled: January 23, 2020Publication date: December 9, 2021Inventors: Steven D. Knutson, Jennifer M. Heemstra

Patent number: 10465242Abstract: Systems, devices, and methods for capturing single source-specific biological material from a multi-source aggregate of biological material are disclosed and discussed. A capture system is generated using reversible chain-blocking to make capture substrates having substrate-linked populations of capture molecules specific for molecules of interest. Incubating such capture substrates in the presence of only a single source of biological material facilitates the association of molecules of interest from the same source. Capture substrate-specific barcode sequences coupled to the capture molecules allow multisource aggregate processing and subsequent grouping to retain the source-specific information following downstream processing.Type: GrantFiled: July 14, 2017Date of Patent: November 5, 2019Assignee: University of Utah Research FoundationInventors: John Phillips, William M. Hanson, Jennifer M. Heemstra

Patent number: 9599628Abstract: Methods, assays, and products for the detection of small molecules are provided. In one aspect, for example, a method of detecting a small molecule in a sample can include reacting together a first half of a DNA split aptamer having a first reactive group coupled thereto, a second half of a DNA split aptamer having a second reactive group coupled thereto, where the DNA split aptamer is selective for the small molecule, and a sample containing the small molecule. The first half and the second half bind to the small molecule and the first reactive group and the second reactive group react to form an aptamer ligation product of the first half and the second half. The method can also include assaying for the aptamer ligation product in order to detect the small molecule presence in the sample.Type: GrantFiled: March 8, 2016Date of Patent: March 21, 2017Assignee: University of Utah Research FoundationInventor: Jennifer M.

Patent number: 8945838Abstract: Methods, assays, and products for the detection of analytes in a sample are provided. In one aspect, for example, a device for detecting an analyte in a sample can include a fluid transfer membrane further including a sample input region operable to receive a liquid sample, a reagent region including a first split aptamer segment, a second split aptamer segment, and a detection marker, where the first and second split aptamers are operable to ligate in the presence of the analyte. The detection marker is operable to bind to the second split aptamer. The device can further include a test region having an immobilized binding reagent operable to bind to the first split aptamer segment such that the detection marker is held in the test region when the first split aptamer segment is ligated to the second split aptamer segment due to the analyte being present in the sample.Type: GrantFiled: May 14, 2013Date of Patent: February 3, 2015Assignee: University of Utah Research FoundationInventor: Jennifer M.
