Basis for DNA ejection from single phage particles
... which is close to ten times the pressure inside a bottle
of champagne. In the new work reported this week, researchers have evaluated whether the energy thus stored is sufficient to permit phage DNA ejection, or only to initiate that process. The researchers used fluorescently labeled phage DNA to investi...
Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections
