Blue Dextrans

Bearing Cibacron Blue F3G-A, blue dextran is used in affinity chromatography and protein chromatography allowing for the identification of proteins (purified or in crude cellular extracts), and improving the purification procedures for various proteins (1), as well as in gel chromatography as molecular weight markers for determining molecular size in each fraction and void volume. These steps are very important to validate fractionation in gel chromatography.  In addition, blue dextran was found to bind to pyruvate kinase 1, and this observation enabled the purification of a whole series of proteins and essentially brought the use of textile dyes in protein purification to the fore (2).  The blue dextrans now extend the range of applications for studies on lysosomal activity (3), endothelial cell permeability (4), bovine sperm permeability (5), cornea permeability (6), flow studies in lung (7-9), cerebro permeability (10-12), binding of proteins and enzymes to Blue-dextran (13-15).
