Our visitors will find in the following listing many of the commonly-used fluorochromes, with their respective peak excitation and emission wavelengths.
While the authors assume responsibility for the accurate reporting of the data as published in various reliable sources, several caveats must be given. Fluorochrome dyes are environmentally sensitive and different results will be obtained with different solvents and applications. In reviewing the literature, you will frequently find somewhat different data supplied for the identical fluorochrome. There are also, in many instances, several sub-varieties of a fluorochrome.
It is strongly urged that the data for a particular fluorochrome be confirmed by consulting the dye manufacturer to secure full specification of curves for excitation and emission.
