Laser flow cytometry
Webb29 maj 2024 · The commonly used laser source of the flow cytometer is the argon laser source that generates lights of the wavelength of 488 nm. The flow cytometers may have other laser sources such as krypton laser, helium–neon lasers, helium–cadmium lasers and UV laser [3, 4]. Table 2.1 shows the wavelength of various laser sources.

WebbHow flow cytometry works. Flow cytometers contain three main systems—fluidics, optics and electronics. The fluidics system funnels a sample of cells (e.g., a sample of human blood) into a single stream so that the cells pass through a laser beam one at a time. As each cell passes through the beam, it scatters light and may emit fluorescent light. la plage south pearlWebbSelect up to five lasers for optimization of your research needs.
