The dyes have been designed for application in the area of life science, e.g. labeling of DNA, RNA and proteins as well as analytical applications, in particular fluorescence microscopy.The ATTO Dye series covers a spectral range from 390 nm in the UV up to 740 nm in the near infrared allowing excitation with most commonly used light sources. The dyes typically are derivatives of coumarins, rhodamines, carbopyronins and oxazines. They are commercially available as free carboxylic acids, amine reactive N-hydroxy-succinimidyl-esters (NHS-ester) or thiol reactive maleimides.Many common fluorescent labels, e.g. Fluorescein (FITC), show rather low photostability.
