This invention relates to SARS-CoV-2 viruses adapted with nanoluciferase reporter molecules and mouse-adapted SARS-CoV-2 viruses, compositions including the same and methods of use thereof.

A method of producing plant virus-like particles includes freeze drying an aqueous solution of plant virus particles to produce a substantially RNA-free plant virus-like particles.

An anti-cancer virus composition including an icosahedral-shaped plant virus or virus-like particle linked to a HER2 antigen is described. The anti-cancer virus composition can be used for methods of treating or decreasing the risk of developing a HER2-expressing cancer in a subject by administering to a subject in need thereof an effective amount of the anti-cancer virus composition.

A detection of optimal genetic recombinants used to prepare target proteins, with assessment of their target-specific upstream productivity, genetic stability and means to optimize target protein downstream purification using customizable fluorescent tags. A scarless removable protein fusion makes it possible to identify recombinants of Pichia pastoris with optimal performance in heterologous protein production.

A method of producing plant virus-like particles includes freeze drying an aqueous solution of plant virus particles to produce a substantially RNA-free plant virus-like particles.

Photodynamic virus particles including a plant virus particle associated with a photosensitizing agent are described. Methods of treating cancer in a subject by administering to the subject a therapeutically effective amount of the photodynamic virus particles and illuminating a cancer-bearing region of the subject to activate the photodynamic virus particles are also described.

The present invention relates to novel fusion polypeptides and the uses thereof. The invention particularly relates to conjugated coat proteins derived from nepoviruses, virus-like particles made with such proteins, and the uses thereof. The particles of the invention can expose and/or encage molecules of interest and have utility in various fields such as the pharmaceutical, agro, or veterinary areas.

A melt processed viral nanoparticle construct for delivery of virus or virus-like particles to a site of interest includes a degradable polymer matrix and a plurality of virus or virus-like particles encapsulated within the degradable polymer matrix. The nanoparticle construct upon administration to the site of interest providing a sustained release of the virus or virus-like particles and/or nanoparticles upon degradation of the polymer matrix.
