WebWhen coupled to recent technical advances in widefield fluorescence and confocal microscopy, including ultrafast low light level digital cameras and multitracking laser control systems, the green fluorescent protein and its color-shifted genetic derivatives have demonstrated invaluable service in many thousands of live-cell imaging experiments. WebAs these cells passed through the stream, the laser light would excite the fluorescent tag, or fluorochrome, which would emit photons of light at a higher wavelength (Fitc emits light at ~530nm when excited by a 488nm laser). This light can be collected and used to further categorize the cells. The figure at the left shows a sample which has ...
