ATTO 647 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, high photo-stability, and good water solubility. ATTO 647 is a zwitterionic dye with a net electrical charge of zero. The dye is stable at physiological pH-values and in buffers up to pH 8. However, it slowly degrades at higher pH. The dye is very hydrophilic. The fluorescence is excited most efficiently in the range 615 - 660 nm. A suitable excitation source for ATTO 647 is, next to the He:Ne laser (633nm), the 647 nm line of the Krypton-Ion laser or a diode-laser emitting at 650 nm.

ATTO 647属于新一代红色光谱区荧光标签。标签的特点是强吸收、高荧光量子产率、高光稳定性和良好的水溶性。ATTO 647是一种两性离子染料，净电荷为零。染料在生理pH值和pH值高达8的缓冲液中是稳定的。然而，它在较高的pH值下缓慢降解。染料非常亲水。荧光在615-660 nm范围内激发最有效。ATTO 647的合适激发源是He:Ne激光器（633nm）旁边的氪离子激光器647nm线或650nm发光二极管激光器。
