Evaluation of APTS-dextran retention using dialysis membranes. (A) Electropherograms of APTS-labeled 6000 MW dextran sample before and after dialysis using a 1000 Da NMCL membrane. Peaks corresponding to dextrans comprised of 4 and 20 glucose units are denoted by arrows. (B) Fractional peak areas corresponding to dextran oligomers retained in 1000 Da NMCL membrane (black squares), 3500 Da NMCL membrane (blue triangles) and undialyzed 6000 Da MW dextran (red circles). (C) Relative retention of dextran by 1000 Da NMCL membrane (squares) and 3500 Da NMCL membrane (circles).
