You can explore our broad selection of catalog dye labeled peptides and amino acids by shifting the pointer of our color range selector to the wavelength range of interest. In case of FRET-pairs, please search for the wavelength of the fluorophore. Alternatively, you can also directly select the name of the chromophore. 


If you are not able to find your specific dye or FRET-labeled catalog product, please request a custom quote
