WebbAbstract. The Gal4/UAS system is a versatile tool to manipulate exogenous gene expression of cells spatially and temporally in many model organisms. Many variations of light-controllable Gal4/UAS system are now available, following the development of photo-activatable (PA) molecular switches and integration of these tools. WebbFollowing are the major difference between photodiode and photomultiplier tube. Photodiode convert one photon into one electron, while photomultiplier amplify electrons. Photomultiplier tube uses detector which changes photons into electrons so that they can be detected. Later photomultiplier tube uses dynodes to amplify the electrons.
