Provided are an anti-RS virus antibody with high sensitivity and a test reagent using the antibody.

An anti-RS virus N protein monoclonal antibody, comprising a heavy chain variable region consisting of the amino acid sequence as set forth in SEQ ID NO: 1, and a light chain variable region consisting of the amino acid sequence as set forth in SEQ ID NO: 2, 3 or 4, or an antigen-binding fragment thereof.

Attenuated isolates of avian reoviruses associated viral arthritis/tenosynovitis in poultry are presented, including avian reovims strain 94826 C140 deposited at the ATCC under Patent Designation PTA-126077 and progeny or derivatives thereof and avian reovims strain 96139 C140 deposited at the ATCC under Patent Designation PTA-126078 and progeny or derivatives thereof. Compositions and methods for administering the isolates or compositions as vaccines to control of reovims-induced viral arthritis/tenosynovitis in birds of the order Galliformes are also presented.

Provided are a highly-sensitive antibody and a test reagent using the antibody.

A method for detecting an analyte according to an immunoassay method, using a carrier on which an antigen, an antibody or an antigen-binding fragment thereof is immobilized, wherein the analyte is detected with increasing detection sensitivity by using a carrier to which an antigen, an antibody or an antigen-binding fragment thereof was immobilized by adding disaccharide and sugar alcohol to a solution comprising an antigen, an antibody or an antigen-binding fragment thereof.

Disclosed are antigen binding polypeptides and antigen binding polypeptide complexes (e.g., antibodies and antigen binding fragments thereof) having certain structural features. Also disclosed are polynucleotides and vectors encoding such polypeptides and polypeptide complexes; chimeric antigen receptors (CARs), cells, pharmaceutical compositions and kits containing such polypeptides and polypeptide complexes; and methods of using such polypeptides and polypeptide complexes.

The present invention relates in part to amino acid sequences that are directed against and/or that can specifically bind to an envelope protein of a virus, as well as to compounds or constructs, and in particular proteins and polypeptides, that comprise or essentially consist of one or more such amino acid sequences.
