Ambient Temperature Stable, Scalable COVID-19 Polymer Particle Vaccines Induce Protective Immunity.

There is an unmet need for safe and effective severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines that are stable and can be cost-effectively produced at large scale. Here, a biopolymer particle (BP) vaccine technology that can be quickly adapted to new and emerging variants of SARS-CoV-2 is used. Coronavirus antigen-coated BPs are described as vaccines against SARS-CoV-2.

Protein Expression in the Baculovirus-Insect Cell Expression System.

The baculovirus-insect cell expression system is a popular choice for recombinant protein production. Post-translational modifications, production of protein complexes, and reported high protein yields are some of the favorable features of this eukaryotic expression system. The intricacies of the baculovirus-insect cell expression system may deter beginners from implementing it for routine protein production.
