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

Patent number: 11035861Abstract: The disclosure is directed to methods and apparatus for the determination, diagnosis, progression and prognosis of kidney disease and mortality associated with kidney disease. The disclosure includes methods for determining renal function, in particular estimating glomerular filtration rate (GFR), in an animal. GFR can be useful in the diagnosis and treatment of kidney disease or dysfunction. In various aspects, the disclosure is directed to the use of free symmetrical dimethylarginine (SDMA) and creatinine in blood samples from animals, in particular cats and dogs, to determine glomerular filtration rate and kidney disease.Type: GrantFiled: March 4, 2016Date of Patent: June 15, 2021Assignee: IDEXX Laboratories, Inc.Inventors: Mahalakshmi Yerramilli, Murthy V S N Yerramilli

Patent number: 9970927Abstract: 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: GrantFiled: February 28, 2014Date of Patent: May 15, 2018Assignee: IDEXX Laboratories, Inc.Inventors: Murthy V.
