CF®DI aminooxy dyes react with aldehyde/ketone groups on proteins or other biomolecules to form a stable oxime bond. The CF®DI dyes (CF®488DI, CF®555DI and CF®647DI) are designed to match each other for molecular weight and charge. The molecular weights of the same protein conjugated to different CF®DI dye colors are close to each other and the pl of the labeled proteins remains the same. • React with carbonyl moieties of aldehyde or ketone groups on proteins and other biomolecules. • Size- and charge-matched fluorescent aminooxy dyes. • Available in 3 colors for multiplex analysis.
