Fluorochrome chart: a complete guide


Fluorescent dyes (also known as fluorochromes) are commonly used as detection reagents in a variety of applications such as cellular imaging and flow cytometry. Fluorochromes absorb light energy of a specific wavelength and re-emit it at a longer wavelength.

The wavelengths at which the fluorochrome absorbs and emits light constitute what is known as the fluorochrome’s excitation and emission spectra respectively (or just fluorescence spectra).
