AT 647 DBCO

中文名稱：AT 647二苯并環(huán)辛炔

化學(xué)式：C52H59N4O5S+

分子量：852.13

結(jié)構(gòu)式：

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.

DBCO試劑是一類含有非常活潑的DBCO（二苯并環(huán)辛炔）基團(tuán)的點(diǎn)擊化學(xué)標(biāo)記試劑，DBCO試劑可以通過無銅點(diǎn)擊化學(xué)與疊氮標(biāo)記分子或生物分子反應(yīng)。DBCO點(diǎn)擊化學(xué)可以在水緩沖液或有機(jī)溶劑中運(yùn)行，具體取決于底物分子的性質(zhì)。帶有PEG臂的試劑將增加化合物的親水性。
