Application

This 488nm absorbing dye is probably the most popular dye in cell biology and represents an alternative to Alexa Fluor 488 and the DyLight 488. Fluorescent dye azides can be used for the fluorescent labeling of terminal alkyne-modified molecules by the Cu(I)-catalyzed azide-alkyne (CuAAC) reaction (click reaction).
