ATTO488™ Lysine Dextran
ATTO488TM-lysine dextran is manufactured by reacting a selected dextran fraction with an ATTO488 derivative. The product is purified from reagents, solvents and by-products. The product is supplied as an orange powder which 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 502 nm and the emission maximum is 524 nm. The fluorophore ATTO488 displays strong absorption, high quantum yield and photo-stability. ATTO488 lysine dextran is stable when stored in well-sealed containers at room temperature in the dark.
