20220056112 · 2022-02-24 ·

The disclosure provides rabbit monoclonal antibodies against the nucleocapsid protein of SARS-CoV-2 and uses thereof. The antibody comprises: a V.sub.H CDR1 selected from the group consisting of SEQ ID NO: 1-7; a V.sub.H CDR2 selected from the group consisting SEQ ID NO: 8-14; a V.sub.H CDR3 selected from the group consisting of SEQ ID NO: 15-21; a V.sub.L CDR1 selected from the group consisting SEQ ID NO: 22-28; a V.sub.L CDR2 selected from the group consisting of SEQ ID NO: 29-35; and a V.sub.L CDR3 selected from the group consisting of SEQ ID NO: 36-42. The antibodies can be used for a rapid test or screening of SARS-CoV-2 infection and detecting SARS-CoV-2 nucleocapsid protein.

High-yield transgenic mammalian expression system for generating virus-like particles
09795666 · 2017-10-24 · ·

Virus-like particles (VLPs) of mammalian-hosted viruses, such as SARS-CoV and influenza viruses, have been recombinantly produced from Vero cells. The VLPs closely emulate the exterior of authentic virus particles and are highly immunogenic. They can elicit not only humoral but also cellular immune responses in a mammal. Compositions and methods related to the VLPs are also described.

Methods and devices for using mucolytic agents including N-acetyl cysteine (NAC)

Devices and methods incorporate mucolytic agents into a point-of-care testing device. The sample is loaded, and then the sample travels until it encounters one or more lysis agents and/or mucolytic agents. The mucolytic agent is preferably pre-loaded onto the collection device. In a preferred embodiment, the mucolytic agent is localized between the sample application zone and the conjugate zone. In embodiments with a sample compressor, one or more mucolytic agents may be pre-loaded and dried on the sample compressor, the sample collector, in various locations on the test strip, or in the running buffer.

SAMPLE TREATMENT SOLUTION, METHOD FOR REMOVING CONTAMINANT PROTEINS AND DETECTION METHOD THEREFOR

According to one embodiment, a sample treatment solution for detecting a detection target contained in a sample, includes a carrier supporting an active ester group.

Signal amplification in lateral flow and related immunoassays

The present invention provides methods, devices, compositions (e.g., capture complexes), and kits useful for enhancing the detection of antibodies in a test sample. The methods, devices, and compositions utilize detectable Fc-binding molecules such as Protein A, Protein G, and/or an Fc-specific antibody to amplify the signal of a detected antibody in immunoassays, such as lateral flow assays.

Novel Immunoassay Platform for the Serological Discrimination of Closely Related Viruses
20230176072 · 2023-06-08 ·

An immunoassay platform and methodology are described for discriminatively detecting target microorganism antibodies to a target antigen in a biological sample derived from a host animal, from among antibodies of cross-reactively-related microorganism(s) potentially present in the biological sample, by use of contemporaneous assays conducted with and without blocking antibodies exogenous to the host animal. Attenuation of detection reagent signal between the contemporaneous assays may be used to determine a target antigen previously infected or non-infected status of the host animal. An assay system is described, including: a single-use cartridge containing test strips constituted to perform the immunoassay; an integrated sample collection and processing device engageable with the single-use cartridge for delivery of sample thereto, and for operatively initiating immunoassay performance in the single-use cartridge; and a portable immunoassay reader for reading immunoassay output signals from the test strips of the single-use cartridge.

Human Ebola virus species and compositions and methods thereof

Compositions and methods including and related to the Ebola Bundibugyo virus (EboBun) are provided. Compositions are provided that are operable as immunogens to elicit and immune response or protection from EboBun challenge in a subject such as a primate. Inventive methods are directed to detection and treatment of EboBun infection.

Anti-influenza B virus neuraminidase antibodies and uses thereof

Provided herein are antibodies that bind to neuraminidase (NA) of different strains of influenza B virus, host cells for producing such antibodies, and kits comprising such antibodies. Also provided herein are compositions comprising antibodies that bind to NA of different strains of influenza B virus and methods of using such antibodies to diagnose, prevent or treat influenza virus disease.
