BDY 630-X, SE,cas:380367-48-6

BDY 630-X, SE is a fluorescent red BDY (BODIPY® or boron-dipyrromethene) dye for the labeling of amines. Displays high fluorescence quantum yield and high extinction coefficient and is relatively insensitive to pH change. This dye contains a seven-atom aminohexanoyl ("X") spacer between the fluorophore and the NHS ester group, reducing the potential for interactions between the fluorophore and conjugated biomolecule.
