This superfine dextran chromatography medium is designed for desalting, peptide separation, biological-extract cleanup, and molecular-weight determination. It uses crosslinked dextran with controlled internal porosity. Molecules are separated according to their relative access to the gel pores. Large molecules are excluded from the particles and elute first. Intermediate molecules enter some pores and migrate more slowly. Smaller molecules access more of the internal matrix and elute last. The 10-40 µm particles support high-resolution fractionation. The stated molecular-weight separation range is 3000-70000 Da.
