ATTO488™-dextran 4 (AT488D4)

ATTO488TM-dextran 4 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 mean average molecular weight is approx. 4000 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 502 nm and the emission maximum is 524 nm. The fluorophore ATTO488 displays strong absorption, high quantum yield and photo-stability. ATTO488 Dextran 4 is stable when stored in well-sealed containers at room temperature in the dark.
