ATTO647n™-Lysine dextran 70 (AT647nLD70)
ATTO647nTM-Lysine dextran 70 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 an blue powder, which is soluble in water. The mean average molecular weight is approx. 70000 Da. The actual 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. ATTO647n Lysine Dextran 70 is stable when stored in well-sealed containers at room temperature in the dark.
