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.
Ezek a technológiák mind  nagyon ígéretesek voltak, de a nehézség az,  hogy vagy nem hatékonyak, vagy annyira bonyolult a használatuk, hogy a legtöbb tudós nem alkalmazza  őket a laboratóriumában, és a klinikai alkalmazásokban sem.
