About Chromeo 494


Chromeo™ 494 is a unique red fluorescent label that is excitable at a wavelength of 488 nm by Argon Laser, LED, Xenon-Arc or Tungsten-Halogen lamps. It has a very large Stokes shift of 134 nm, making it an ideal partner for multiplexing in immunofluorescence experiments, especially in combination with Chromeo 488. While both dyes are readily excited at 488 nm, the fluorescent emission of Chromeo 488 at 517 nm is easily distinguished from the emission of Chromeo 494 at 628 nm. This long Stokes shift eliminates signal overlap caused by bleed-through between the detection channels in multiplexing experiments.
