BDP 630/650 maleimide,激發(fā)/發(fā)射630/650
目前Cyanine系列染料以兩種異構(gòu)體的形式存在，一種是非磺化花青素（non-sulfonated cyanines），一種是磺化花青素（sulfonatedcyanine）。兩者的光譜性質(zhì)幾乎*，因此大部分應(yīng)用可相互替換。

BDP 630/650 maleimide

BDP 630/650 is a far red emitting borondipyrromethene based fluorophore for the Cyanine5 channel. Because of its relatively long lifetime of the excited state, this dye is particularly useful for fluorescence lifetime related measurements.

The reactive maleimide moiety allows to attach the dye to thiol groups in biomolecules, especially proteins and peptides.
