產(chǎn)品名稱：ATTO 647 Acid

AT 647 carboxylic acid

AT 647 COOH

中文名稱：AT 647羧酸

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屬于新一代紅色光譜區(qū)熒光標記。該標記的特點是強吸收、高熒光量子產(chǎn)率、高光穩(wěn)定性和良好的水溶性。ATTO 647是一種兩性離子染料，凈電荷為零。染料在生理pH值和pH值高達8的緩沖液中是穩(wěn)定的。然而，它在較高的pH值下緩慢降解。染料非常親水。熒光在615-660 nm范圍內(nèi)激發(fā)最有效。ATTO 647的合適激發(fā)源是He:Ne激光器（633nm）旁邊的氪離子激光器647nm線或650nm發(fā)光二極管激光器。
