Abstract: The present invention provides an immunological detection method for trimeric type I collagen N-terminal propeptide in a biological sample, which uses a first antibody that binds to a specific portion of a pro-?1 chain in the trimeric type I collagen N-terminal propeptide and a second antibody that binds to a specific portion of a pro-?2 chain in the trimeric type I collagen N-terminal propeptide. The immunological detection method is easy to handle and can specifically (selectively) measure the trimer in biological samples containing the trimer and monomer of the ?-chain of PINP.

Abstract: The present invention provides an immunoassay method for assaying SARS-CoV-2, including a step of contacting a biological sample with a monoclonal antibody or an antibody fragment thereof that binds to a nucleocapsid protein of SARS-COV-2, wherein the monoclonal antibody or the antibody fragment thereof binds to the SARS-CoV-2 treated with a serine protease.

Abstract: The problem addressed by the present invention is to provide an immunological assay method using a monoclonal antibody and a kit including the monoclonal antibody, which can be used for assaying ICTP without requiring special facilities. This problem can be solved by a method for immunological assay of type I collagen C-terminal telopeptide in a biological sample, including contacting type I collagen C-terminal telopeptide with a monoclonal antibody that recognizes an amino acid sequence represented by GFDFSFLP (SEQ ID NO: 1) as an epitope.

Abstract: A problem to be solved by the invention is to improve the sensitivity of measurement of an analyte in a sample by a sandwich immunoassay. The sensitivity can be improved significantly in a sandwich immunoassay using a first antibody and a second antibody when one or both of the first antibody and the second antibody are a mixture of a monoclonal antibody recognizing a linear epitope and a monoclonal antibody recognizing a conformational epitope.

Abstract: A problem to be solved is to detect only free AIM in a biological sample containing complex AIM and free AIM. The problem can be solved by an immunoassay method for free AIM in a biological sample using an anti-AIM monoclonal antibody having a property of reacting with free AIM and not reacting with complex AIM, wherein the anti-AIM monoclonal antibody is an antibody binding to an epitope in the SRCR2 domain of human AIM.

Abstract: A problem to be solved is to further improve the specificity for free AIM of an antibody specifically reacting with free AIM and to diagnose NASH without imposing a burden on patients and medical staffs. The problem can be solved by an immunoassay method for free AIM in a biological sample containing complex AIM and free AIM, and the method comprises bringing the biological sample into contact with an antibody specifically reacting with free AIM in a presence of an anti-IgM antibody.
