Abstract: The present invention relates to a method of determining an analyte in a sample, said method comprising (a) contacting said sample with (i) a binding compound binding to said analyte, said binding compound comprising a binding agent and a first partner of an affinity pair (first affinity partner); and (ii) a second partner of the affinity pair (second affinity partner) coupled to a solid surface, to an indicator, and/or to a second binding agent; and (b) determining said analyte based on complexes formed in step (a); wherein one of said first affinity partner and said second affinity partner is a polypeptide comprising the amino acid sequence of SEQ ID NO:1 or a sequence at least 50% identical thereto, and wherein the other of said first affinity partner and said second affinity partner is a polypeptide comprising the amino acid sequence of SEQ ID NO:2 or a sequence at least 50% identical thereto.

Abstract: The present invention relates to monoclonal antibodies binding to the nucleocapsid protein of SARS-CoV-2 virus, nucleic acids encoding said antibody, host cells producing the same, compositions and kits comprising said antibodies, as well as methods of detecting SARS-CoV-2 virus in a sample comprising using said antibodies.

Abstract: The present invention relates to a method for assessing atrial fibrillation in a subject, said method comprising the steps of determining the amount of BMP10 in a sample from the subject, and comparing the amount of BMP10 to a reference amount, whereby atrial fibrillation is to be assessed. Moreover, the present invention relates to a method for diagnosing heart failure based on the determination of BMP 10 in a sample from a subject. Further, the present invention relates to a method for predicting the risk of a subject of hospitalization due to heart failure based on the determination of a BMP10-type peptide in a sample from a subject. The present invention further pertains to antibodies which bind to one or more BMP10-type peptides such as NT-proBMP10.
