Descripción general

Blue Dextran is a soluble derivative of dextran. Its structure includes triazinyl dye Cibacron blue F3GA covalently bound to high molecular weight (2000 kDa) dextran. Blue Dextran is generally used as a marker to determine void volume in gel filtration chromatography columns.

Aplicación

Blue Dextran has been used for calibration of size exclusion chromatography (SEC) column. It has also been used in Dextran blue permeability assays to determine the integrity of co-cultures containing epithelial cells. Blue dextran may be used in affinity chromatography, gel filtration chromatography, protein chromatography, and molecular weight markers. Blue dextran is also suitable to study Alzheimer′s disease.
