Scientists are reporting discovery of a way to help proteins such as the new generation of protein-based drugs -- sometimes heralded as tomorrow's potential "miracle cures" -- get past the biochemical "Entrance Forbidden" barrier that keeps them from entering cells and doing their work. The new technique, described in the monthly journal, ACS Chemical Biology, represents a new use for an engineered form of green fluorescent protein, the topic of the 2008 Nobel Prize in Chemistry that is one of the most important research tools in biosciences.
