ATTO 633

ATTO 633 属于红色光谱区域的新一代荧光标记物。 Characteristic features of the label are strong absorption, high 荧光量子产率, and high thermal and photo-stability. Thus ATTO 633 is highly suitable for single-molecule detection applications and high-resolution microscopy such as SIM, STED etc. Additionally the dye highly qualifies to be applied in flow cytometry (FACS), fluorescence in-situ hybridization (FISH and many more.

In common with most ATTO-TEC-labels, absorption and fluorescence are independent of pH, at least in the range of pH 2 to 11, used in typical applications. ATTO 633 是一种cationic dye. After coupling to a substrate the label carries a net electrical charge of +1.

The label is moderately 亲水性. Its fluorescence is excited most efficiently in the range 610 - 645 nm. A suitable excitation source for ATTO 633 is the 633 nm line of the He:Ne laser or a diode-laser emitting at 635 nm.
