Virginia Tech Researchers Receive Patent For Rapid Virus Detection Technology

...en its host, E. coli must also be present. "An advantage of the rapid virustest is that viruses are usually live longer in water samplesthan bacterial cells, thus presence of virus can indicate previousfecal contamination of water after living cells have died,"says Falkinham. Further, the bacterial viruses...

Recombinant Protein Immunizes Mice, Promises New Strategy Against Infection And Cancer

... "We were able to solve this problem by taking advantage of theobservation that a class of proteins, called heat-shock proteins, are exceptionsto the rule that soluble proteins are unable to stimulate CTL responses. Infact, heat-shock proteins are extremely potent in stimulating a CTL immuneresponse," says...
