摘要:
The present invention relates to an ultrasensitive rapid antigen detection kit for detecting N protein from SARS-CoV-2 virus in a sample, and methods for detecting N protein. The kit includes a sample collector, a collection and enrichment tube and a rapid antigen detection component with a test strip. The collection and enrichment tube contains a first part containing lyophilized ATPS reagents and a second part containing a lysis buffer. The sample is mixed with the lyophilized ATPS reagents and the lysis buffer to form a mixture. The enrichment is realized by concentrating the target analyte into one of the two phases formed by ATPS.
摘要:
Provided in the present disclosure is an antibody or an antigen-binding fragment thereof that binds to the respiratory syncytial virus F protein. Further provided in the present disclosure is the use of the antibody or the antigen-binding fragment thereof in the preparation of a drug for the treatment and/or prevention of RSV infections.
摘要:
The disclosure provides isolated antibodies and antigen-binding fragments that bind to the G protein of RSV and which are capable of neutralizing RSV.
摘要:
The present invention provides fully human antibodies that bind to respiratory syncytial virus F protein, compositions comprising the antibodies and methods of use. The antibodies of the invention are useful for preventing fusion of the virus with the cell membrane and preventing cell to cell spread of the virus, thereby providing a means of preventing the infection, or treating a patient suffering from the infection and ameliorating one or more symptoms or complications associated with the viral infection. The antibodies may also be useful for diagnosis of an infection by RSV.
摘要:
The disclosure relates to isolated antibodies and antigen-binding fragments that bind to the G protein of RSV and which are capable of neutralizing RSV A and B subtypes, and the use thereof in the diagnosis, prophylaxis, and/or treatment of RSV infections.
摘要:
The invention provides RSV fusion (F) protein ectodomain polypeptide sequences and nucleotide sequences encoding them, as well as cells containing the invention's polypeptide and nucleotide sequences. The invention further provides VLPs that contain the invention's polypeptides, and methods for using the VLPs for protein expression and vaccine formulation. Also provided are methods for distinguishing between subjects immunized with the invention's compositions and subjects infected with RSV.
摘要:
The present invention describes a liquid direct fluorescence antibody assay that is rapid and sensitive to detect respiratory virus in infected cells. The assay includes centrifugation of the specimen, incubation of sample and reagents in solution, and detection of the absence or presence of respiratory virus. Sapogenin is used as a detergent to permeabilize the cells for entry of the monoclonal antibodies to react with intracellular antigens. The cells are stained with fluorescently labeled monoclonal antibodies against the viral antigens along with a background stain and a fluorescent nuclear stain. This counter staining decreases background and allows co-localization of antigen and nuclear structures for enhanced detection.
摘要:
Multiplexed test measurements are conducted using an assay module having a plurality of assay domains. In preferred embodiments, these measurements are conducted in assay modules having integrated electrodes with a reader apparatus adapted to receive assay modules, induce luminescence, preferably electrode induced luminescence, in the wells or assay regions of the assay modules and measure the induced luminescence.

摘要:
The invention concerns a method for the extraction of nucleic acids from biological samples e.g. tissue material or sputum derived from human or animal species and the quantitative detection thereafter of said nucleic acids e.g. in terms of viral load, more specifically RSV viral load detection.
