ATTO 610 belongs to a new generation of fluorescent labels for the red spectral region. Characteristic features of the label are strong absorption, high fluorescence quantum yield, and high thermal and photo-stability.
The dye is moderately hydrophilic. The dye is stable under physiological pH-values and in buffers up to pH 8. However, it slowly degrades at higher pH. The fluorescence is excited most efficiently in the range 595 - 625 nm.
