20210302417 | COMPLEX STABILIZING COMPONENTS AND DETECTION METHODS THEREOF - The disclosure provides an in vitro diagnostic method that is sensitive and accurate for detection and quantification of targets of interest that are associated with disease. There is an ongoing need for a highly sensitive detection system. In addition to the methods, stable complexes and kits comprising the components necessary to perform the disclosed detection methods are described. | 2021-09-30 |
20210302418 | ULTRASENSITIVE DETECTION OF VIRUS PARTICLES AND VIRUS-LIKE PARTICLES - The present invention relates to a method for quantitatively and/or qualitatively determining virus particles containing at least one binding site for a capture molecule and at least one binding site for a probe, to a kit for carrying out said method, and to various uses. | 2021-09-30 |
20210302419 | METHODS AND DEVICES FOR USING MUCOLYTIC AGENTS INCLUDING N-ACETYL CYSTEINE (NAC) - Devices and methods incorporate mucolytic agents into a point-of-care testing device. The sample is loaded, and then the sample travels until it encounters one or more lysis agents and/or mucolytic agents. The mucolytic agent is preferably pre-loaded onto the collection device. In a preferred embodiment, the mucolytic agent is localized between the sample application zone and the conjugate zone. In embodiments with a sample compressor, one or more mucolytic agents may be pre-loaded and dried on the sample compressor, the sample collector, in various locations on the test strip, or in the running buffer. | 2021-09-30 |
20210302420 | DIAGNOSTIC METHOD FOR SYSTEMIC LUPUS ERYTHEMATOSUS USING SMYD3 AUTOANTIBODY - A method of diagnosing systemic lupus erythematosus using an antigen protein that binds specifically to an SMYD3 autoantibody present in body fluid of a patient with systemic lupus erythematosus. The diagnostic method uses a non-invasive biological sample such as blood, and thus may diagnose systemic lupus erythematosus very conveniently without burdening the patient, unlike conventional methods. In addition, the method has high specificity and sensitivity, and thus may be effectively used for early diagnosis of systemic lupus erythematosus. | 2021-09-30 |
20210302421 | METHODS FOR DETECTING ANTI-DRUG ANTIBODIES - In certain embodiments, the present invention provides a method for detecting an anti-drug antibody (ADA) in a sample, comprising: a) pre-treating the sample at a high temperature to dissociate the ADA:drug immune complex in the sample; b) isolating the ADA from the sample by a matrix; c) retrieving the ADA from the matrix using a buffer; and d) detecting the ADA in a cell-based assay or an in vitro assay. | 2021-09-30 |
