The US Food and Drug Administration does not want Rotarix, the rotavirus vaccine, to be used because it contains porcine circovirus 1 DNA. If complete copies of the circovirus genome were present, would they constitute a potential threat to recipients? Put another way, is circovirus DNA infectio... Read More
While almost every lab has a small toolbox with some screwdrivers, pliers, and such, here are some tools that may not have obvious utility at the bench, but could make your life easier.
