Imaging: The DNA Facility has two Typhoon Trio, that can be used for phosphor or fluor imaging. Phosphor imaging is an indirectly measure of radioactive signal from a gel or membrane. Samples are exposed to a phosphor screen and the excited state of the phosphor is read by a laser. With fluor imaging gels, membranes, TLC plates, and microtiter plates can be scanned directly. Filters are used to distinguish between fluorescent dyes and more than one dye can be seen in a sample.
For imaging Western blots or protein gels the Odyssey by LiCor is a great choice. The Odyssey detects IR dyes that allow it to be more quantitative and sensitive than other methods.
