Abstract: A paramyxovirus vaccine strain for novel coronavirus pneumonia and a construction method thereof are provided. The method includes performing a recombination of N and F genes of Newcastle disease virus type VII of Paramyxoviridae with P, M, H, L genes of Canine distemper virus of Paramyxoviridae to obtain a recombinant virus, inserting S1 gene of the novel coronavirus between the P and M genes of the recombinant virus to obtain a recombinant vector. The vaccine strain constructed can stably and efficiently express the novel coronavirus S1 protein, and induce the body to produce antibodies; and the recombined virus vaccine strain can stimulate the human body to produce mucosal immunity, and the prepared vaccine can be vaccinated through a nasal spray. Moreover, the vaccine strain can be tested in poultry and dogs, saving time, reducing costs, and being more conducive to actual production due to large output.

The nanoparticle construct upon delivery to a subject can provide a sustained release of the cowpea mosaic virus or virus-like particles and/or G4 dendrimers to a cell or tissue of the subject. The cancer selected from the group consisting of melanoma, breast cancer, colon cancer, lung cancer, and ovarian cancer.

Abstract: Disclosed is producing recombinant SARS-CoV-2 spike protein in a pre-fusion state, using furin knock out or knockdown mammalian cells (such as HEK293, CHO or other mammalian cells) and using them to generate antibodies and related binding agents. The antibodies/binding agents can be used in SARS-CoV-2 detection assays or in diagnosis of active or prior infection with SARS-CoV-2; in prophylaxis or as a therapeutic; or for prophylactic or therapeutic use against coronaviruses related to SARS-CoV-2.

Abstract: The present disclosure relates generally to genetically tagged bacterial delivery vehicles comprising unique tracer nucleic acid sequences (herein referred to as “tracers”) for use in detecting and/or quantitating the presence of two or more different said bacterial delivery vehicles within a mixture of vehicles. The present disclosure relates to methods wherein the bacterial delivery vehicles are detected through, for example, performance of multiple cycles of amplification using primers that bind to sequences within the unique tracer. Such methods can be advantageously used in quality control to detect and quantitate mixtures of bacterial delivery vehicles within a pharmaceutical composition.
