The present invention relates to an anti-SARS-CoV-2 S protein-specific antibody or an antigen-binding fragment thereof, and therapeutic and diagnostic uses thereof. The anti-SARS-CoV-2 S protein-specific antibody or antigen-binding fragment thereof according to the present invention can bind specifically to the S protein, which plays an important role in the infiltration of SARS-CoV-2 into host cells, to inhibit the infection of SARS-CoV-2, and thus can be advantageously used as a therapeutic agent for COVID-19 and as a diagnostic agent and diagnostic kit for COVID-19.

Provided is a multivalent protein that targets interaction of SARS-CoV-2 spike receptor binding domain (RBD) with the human angiotensin-converting enzyme 2 (ACE2) receptor protein. The multivalent proteins may also be used to treat subjects having cancer and/or a disease and/or viral infection. Also presented is a multiplex lateral flow test strips for simultaneous detection of the virus and viral antibodies.

The present invention relates to a vaccine for Zika virus, the vaccine comprising Zika virus membrane and envelope proteins. More specifically, the vaccine comprises nucleic acid molecules encoding modified Zika virus membrane and/or envelope proteins. When introduced into a cell, the encoded proteins are produced, which results in the production of a virus-like particle capable of eliciting an immune response against Zika virus.

A lateral flow assay is capable of detecting and differentiating viral and bacterial infections. A combined point of care diagnostic device tests markers for viral infection and markers for bacterial infection, to effectively assist in the rapid differentiation of viral and bacterial infections. In some preferred embodiments, bimodal methods and devices determine if an infection is bacterial and/or viral. A dual use two strip sample analysis device includes a first lateral flow chromatographic test strip to detect MxA and a low level of C-reactive protein and a second lateral flow chromatographic test strip to detect high levels of C-reactive protein. In some preferred embodiments, the sample is a fingerstick blood sample.

This document provides methods and materials related to treating a disease. For example, this document provides methods for treating a subject's disease based on identifying the risk of progressive multifocal leukoencephalopathy PML using a genetic test.

The present disclosure provides methods for determining the presence or absence of and/or the etiology of an acute respiratory viral infection in a subject, as well as methods of treating the subject based on the determination, by measuring on a platform the expression levels of a pre-defined set of gene products.

The present invention relates to anti-virus dengue virus antibodies and applications thereof. Specifically, the anti-virus dengue virus antibodies of the present invention are serotype specific and useful for specific detection and differentiation of various dengue virus serotypes in a biological sample. The present invention also provide methods and kits for detecting dengue virus and methods and compositions for use in diagnosis and treatment of dengue virus disease using the anti-virus dengue virus antibodies as described herein.

A system comprising a respirator, a biochip, and an atomizer for studying respiratory pathogens. The respirator of the system is configured to create breathe-mimicking air movement, the biochip comprises an airway lumen in fluid communication with the respirator, and the atomizer is in fluid communication with the airway lumen of the biochip, according to various embodiments. The atomizer may be configured to generate droplets of a respiratory pathogen (e.g., from liquid inoculum). In various embodiments, the breath-mimicking air movement comprises air volume as a function of time, wherein the respirator is configured to generate breathing cycles.

Provided herein are compositions, methods, and kits for detecting human Pegivirus 2 (HPgV-2). In certain embodiments, provided herein are HPgV-2 specific nucleic acid probes and primers, and methods for detecting HPgV-2 nucleic acid. In other embodiments, provided herein are HPgV-2 immunogenic composition compositions, methods of treating a subject with immunogenic HPgV-2 peptides, and methods of detecting HPgV-2 subject antibodies in a sample.

The present disclosure is directed to antibodies binding to human respiratory syncytial virus F protein, including both neutralizing and non-neutralizing antibodies, and methods for use thereof.
