Antibody capable of binding to norovirus, composite, detection device and method using the same
The present invention provides a novel antibody capable of binding to a norovirus. The present invention is an antibody that consists of an amino acid sequence, wherein said amino acid sequence consists of, in an N- to C-direction, the following structural domains:
N-FR1-CDR1-FR2-CDR2-FR3-CDR3-FR4-C
wherein FR denotes a framework region amino acid sequence and CDR denotes a complementary determining region amino acid sequence; the CDR1 consists of any one of an amino acid sequences represented by SEQ ID NO: 1-SEQ ID NO: 6; the CDR2 consists of any one of an amino acid sequences represented by SEQ ID NO: 7-SEQ ID NO: 12; the CDR3 consists of any one of an amino acid sequences represented by SEQ ID NO: 13-SEQ ID NO: 17; and the antibody is capable of binding to a norovirus.
Flow cytometry evaluation of biological material for exosome particles
A method for evaluating a biological material for unassociated virus-size particles of exosomes having a particular epitope uses a fluorescent antibody stain specific for binding with the epitope and a fluid sample with the exosomes and fluorescent antibody stain is subjected to flow cytometry with identification of fluorescent emission detection events indicative of passage through a flow cell of a flow cytometer of unassociated labeled particles of virus size including such an exosome and fluorescent antibody stain.
METAPNEUMOVIRUS STRAINS AND THEIR USE IN VACCINE FORMULATIONS AND AS VECTORS FOR EXPRESSION OF ANTIGENIC SEQUENCES
Provided is an isolated mammalian negative strand RNA virus, metapneumovirus (MPV), within the sub-family Pneumoviridae, of the family Paramyxoviridae. Also provided are isolated mammalian negative strand RNA viruses identifiable as phylogenetically corresponding or relating to the genus Metapneumovirus and components thereof. In particular, provided is a mammalian MPV, subgroups and variants thereof. Also provided are genomic nucleotide sequences of different isolates of mammalian MPV, in particular, human MPV. Disclosed is the use of the sequence information of different isolates of mammalian MPV for diagnostic and therapeutic methods. Provided are nucleotide sequences encoding the genome of an MPV or a portion thereof, including both mammalian and avian MPV. Further described are chimeric or recombinant viruses encoded by the nucleotide sequences and chimeric and recombinant mammalian MPV that comprise one or more non-native or heterologous sequences. Also provided are vaccine formulations comprising mammalian or avian MPV, including recombinant and chimeric forms thereof. The vaccine preparations encompass multivalent vaccines, including bivalent and trivalent vaccine preparations.
Immunoassay for Detecting Zika Virus Infection
The present invention relates to a method for detecting Zika virus (ZIKV) infection in a biological sample from a subject. The method comprises testing the sample for IgM- and IgG-ZIKV NS1 antibodies and determining the ZIKV IgM and ZIKV IgG signal intensities; and scoring the sample as positive or negative for ZIKV infection based on the combined results of such determinations. The biological sample is preferably blood, serum, plasma, cerebrospinal fluid, saliva or urine.
ANTIBODY, COMPOSITE, DETECTION DEVICE AND METHOD USING SAME
The present invention is an antibody including an amino acid sequence, wherein the amino acid sequence includes, in an N- to C-direction, the following structural domains:
N-FR1-CDR1-FR2-CDR2-FR3-CDR3-FR4-C
wherein FR denotes a framework region amino acid sequence and CDR denotes a complementary determining region amino acid sequence; the CDR1 includes an amino acid sequence represented by SEQ ID NO: 1; the CDR2 includes an amino acid sequence represented by SEQ ID NO: 2; and the CDR3 includes an amino acid sequence represented by SEQ ID NO: 3.
The antibody is capable of binding to an intranuclear protein of an influenza virus.
Single Domain Antibodies to Chikungunya Virus
Described herein are single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Chikungunya Virus (CHIKV).
