藍(lán)色葡聚糖 2000 Dextran Blue 2000
CAS Number: 87915-38-6
Storage Temperature: Room Temperature
Product Description :
The most common use for Blue Dextran is in the determination of the void volume in gel filtration chromatography columns. It is typically used at 1 mg/ml to 2 mg/ml in a buffer such as 50 mM Tris-HCl, pH 7.5 containing 100 mM KCl. The volume of the Blue Dextran sample should be 1% to no more than 3% of the column's bed volume. The shape of the Blue Dextran band as it elutes through the column can also be used to assess the column packing and resolution.
Blue Dextran has also been used as a spectrophotometric substrate for dextranase. Dextranase activity is measured by the increase in absorbance at 610 nm.
