A chemiluminescence immunochromatographic detection assay, comprising a solid membrane, a capture agent, a chemiluminescent conjugate, a testing buffer, a chemiluminescent reaction solution and a chemiluminescent reader. The capture agent is coated on the solid membrane, the chemiluminescent flows through the solid membrane and absorbed in a water absorbent structure, and the target analyte is captured and immobilized by capture agent on the solid membrane, and the uncapped chemiluminescent conjugate is cleaned up by testing buffer through the solid membrane, The complex of chemiluminescent conjugate and target analyte be immobilized on the solid membrane and placed for the quantitative detection of the light by the chemiluminescent reaction solution and the chemiluminescent reader, and complete the quantitative detection. This technology is suitable for chemiluminescent immunochromatographic detection of various analyte immune analysis, and is characterized as high efficiency, convenience, accuracy and high speed in important clinical application.

The invention provides an assay method for an assay system using an anti-immunocomplex antibody, which is able to increase reaction efficiency. The n immunoassay method uses: an anti-hapten rabbit monoclonal antibody immobilized on a water-insoluble carrier, and a labeled anti-immunocomplex antibody,
wherein the method comprises the following steps (i) to (iii): (i) a step of reacting the anti-hapten rabbit monoclonal antibody immobilized on the water-insoluble carrier with a hapten in a solution to be measured, (ii) a step of reacting the labeled anti-immunocomplex antibody with the hapten-anti-hapten rabbit monoclonal antibody immune complex, and (iii) a step of detecting the signal from the label.

Detectors and related methods and systems are described, based on a primary binding compound and a secondary binding compound used in combination with a support to detect a target in a sample.

Biological assay systems, methods, and devices for detecting the presence of the virus responsible for COVID-19 (sars-cov-2) in the saliva of an individual. The systems, methods, and devices utilize immunoassay technology for detecting the presence of antigen in a sample, such as the virus responsible for COVID-19 in the saliva of an individual. The immunoassay technology in accordance with embodiments of the systems, methods, and devices use nano-carbon, or carbon nanoparticles attached to biorecognition/detector molecules, such as antibodies.

The disclosure provides methods for selecting patient sub-populations, or subjects, with inflammatory conditions such as inflammatory bowel diseases that are amenable to treatment with anti-Interleukin-23 therapy by measuring the serum levels of Interleukin-22 Binding Protein and/or the serum levels of Interferon-γ. In addition, the methods are useful in identifying sub-populations of patients with inflammatory disorders, such as psoriasis, psoriatic arthritis, rheumatoid arthritis, ankylosing spondylitis that are amenable to treatment with an anti-IL-23 therapy and/or an anti-IFN-γ therapy.

A method for predicting or prognosticating the response of individuals with multiple sclerosis to treatment with IFNβ, kit or device, and uses.

A kit for detecting an antigen from which false positive signals are removed is provided. The kit includes a substrate; a capture antibody attachable onto the substrate and having a capture strand labeled with a fluorescent material; a detection antibody having a detection strand labeled with a fluorescent material and complementary to some or all of a base sequence of the capture strand; and a blocking strand having a base sequence capable of complementary binding to the capture strand or the detection strand to prevent the detection strand and the capture strand from complementary binding to each other.

The present invention is intended to provide a novel biomarker capable of detecting aortic aneurysm with high sensitivity, and specifically, the present invention relates to a detection marker of aortic aneurysm, comprising an NPC2 (Niemann-Pick disease type C2) protein and/or an IGFBP7 (Insulin-like growth factor-binding protein 7) protein.

An object of the invention is to provide a method for detecting cancer in a simple and highly accurate manner, and a reagent that can be used in the method. A method for detecting cancer (excluding renal cell cancer), which comprises measuring the level of Azurocidin (AZU1) in a sample, in which it is determined that cancer is detected when a measured value exceeds a preset reference value. The cancer is preferably selected from the group consisting of stomach cancer, breast cancer, colorectal cancer, and lung cancer. A reagent containing an antibody that specifically recognizes AZU1 is used in detecting cancer (excluding renal cell cancer).

The present invention relates to methods of assessing whether a patient has endometriosis or is at risk of developing endometriosis, to methods of selecting a patient for therapy, and method of monitoring a patient suffering from endometriosis or being treated for endometriosis by determining the amount or concentration of S100A6 in a sample of the patient, and comparing the determined amount or concentration to a reference.
