Patent number: 11422136Abstract: The disclosure generally relates to the detection of symmetrical dimethylarginine (SDMA). More particularly, the disclosure relates to the detection of SDMA using a solid phase. The disclosure provides devices, reagents, kits and methods for detecting symmetrical dimethyl arginine (SDMA) in sample, such as a biological sample from an animal. The method includes detecting the presence or amount of SDMA in the sample by using an immunoassay format, such as a competitive immunoassay. The assay includes the use of antibodies to SDMA that are specific for SDMA and that have less affinity for other arginine derivatives.Type: GrantFiled: October 19, 2018Date of Patent: August 23, 2022Assignee: IDEXX Laboratories, Inc.Inventors: Hongzhi Xie, Sreenivasa Rao Ramisetty, Murthy V S N Yerramilli

Publication number: 20220221446Abstract: Method of detecting Symmetrical dimethyl arginine (SDMA) in biological samples. SDMA analogs for generating anti-SDMA antibodies having little or no cross-reactivity with asymmetrical dimethyl arginine, arginine, and monomethylarginine. The analogs have a protected or free thiol (—SH) group or hydroxyl (—OH) group that allow them to be linked to a suitable conjugation target which can be, for example, a protein containing molecule of a label. The anti-SDMA antibodies can be used in diagnostic immunoassay for the diagnosis of SDMA associated disorders and/or diseases.Type: ApplicationFiled: March 28, 2022Publication date: July 14, 2022Inventors: Murthy V.S.N.

Publication number: 20210275979Abstract: A method using a chemical analyzer for removing a component of a liquid sample which may interfere with a test performed on a test assay includes the steps of adding the liquid sample to a sample cup, transferring a volume of the liquid sample to a mixing cup containing an IMAC (Immobilized Metal Affinity Chromatography) resin containing porous beads to form a sample/resin solution in the mixing cup, using a pipette of the chemical analyzer to repeatedly aspirate the sample/resin solution into a disposable pipette tip of the pipette and expelling the sample/resin solution from the pipette tip into the mixing cup to achieve a mixed sample/resin solution in the mixing cup, and allowing the mixed sample/resin solution in the mixing cup to rest undisturbed so that the interfering component of the liquid sample adheres to the porous beads and the beads settle to a bottom portion of the mixing cup, resulting in a refined liquid sample devoid of the interfering component and occupying an upper portion of the mixingType: ApplicationFiled: March 8, 2021Publication date: September 9, 2021Inventors: Pamela Ann Cacavas, Lucius S. Fox, Robert W. Lachapelle, Wendy O'Malley LePage, Evan M. Peck, Dominic Pelletier, Eric Allen Steva, Murthy V.S.N. Yerramilli
