Sephadex™ is a gel filtration resin prepared by crosslinking dextran with epichlorohydrin. Different types of Sephadex™ differ in their degree of cross-linking and hence in their degree of swelling and their molecular fractionation range. Sephadex™ G-75 is one of six different G-types ranging from G-10 for small molecules to G-100 for very large molecules. Sephadex™ G-75 Superfine has the smallest bead size for higher efficiency with shorter diffusion distances.
