graph of emission spectra for eFluor 506 dye

The eFluor 506 organic dye is a violet-laser excitable fluorophore that has an emission peak of 506 nm. With similar spectra characteristics to AmCyan and Horizon V500, conjugates of the eFluor 506 dye require no change to your instrument configuration for use.

Benefits of eFluor 506 include

  • Direct alternative for AmCyan and Horizon V500 fluorophores
  • Similar or better fluorescence intensity than other 500 nm-emitting organic dyes
  • When combined with all five Super Bright dye antibody conjugates, can provide 6 detection channels of the violet laser
