ATTO647n™ Lysine Dextran
ATTO647nTM-Lysine dextran is manufactured by reacting a selected dextran fraction with an ATTO647n derivative. The product is purified from reagents, solvents and by-products. The product is supplied as a blue powder that is soluble in water. The molecular weight is measured by gel permeation chromatography (GPC). The degree of substitution is between 0.001-0.008. The absorption maximum is 646 nm and the emission maximum is 664 nm. The fluorophore ATTO647n displays strong absorption, high quantum yield and photo-stability. ATTO 647n Lysine dextran is stable when stored in well-sealed containers at room temperature in the dark.
