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. Webb1 dec. 2001 · Microarrays were imaged using a ScanArray 5000 laser scanner (GSI Lumonics, Billerica, MA). Except where mentioned, the instrument was set at 60% laser and 60% photomultiplier tube (PMT). Images were analyzed with the QuantArray Image Analysis software package (GSI Lumonics) using the fixed circle method.

WebbTransient NP loading in HPCs. The interaction of HPCs with NPs was evaluated by exposing the cells to fluorescently labeled YG-PS NPs with the concentration range of 5–90 μg mL −1.After 24 hours of continuous exposure, the cellular NP load was evaluated by measuring GMFI using flow cytometry ().HPCs displayed an almost linear loading profile … WebbThe emissions passing through the optical path were acquired by a highly-sensitive photomultiplier tube (PMT) (HSPMT, 160–930 nm). Locating the fast axis of the quarter-wave plate by ± 45 ° with respect to the polarization axis of the linear polarizer can selectively extract the LCP and the RCP components.
