The dangers of virus-based lab research

With the emergence of antibiotic-resistant bacteria and diseases like the Ebola virus, biological laboratories across the globe have intensified their research efforts. Lab work, which often requires technicians to handle caustic chemicals and deadly pathogens, endangers not only lab employees but also the general population, as one mishandled sample could cause a pandemic. As a

Why the VSV delta G system helps study viruses safely

The VSV delta G system, like many other expression vectors, is leading the way in how scientists safely learn about a collection of viruses. Expression vectors are plasmids or viruses used for protein expression in cells. These plasmids or viruses are specifically developed so that they can introduce a certain gene to a target cell.
