And these technologies were very promising, but the problem was that they were either inefficient, or they were difficult enough to use that most scientists had not adopted them for use in their own laboratories, or certainly for many clinical applications.
И тези технологии бяха много обещаващи, но проблемът с тях бе, че бяха или недостатъчни, или твърде трудни за употреба, така че повечето учени не ги бяха възприели в собствените си лаборатории, или поне не се използваха при много от клиничните случаи.
