Merck, G5080-50G, Sephadex® G-50

Sephadex G-50 Fine is a widely used gel filtration resin designed for desalting and buffer exchange of biomolecules with a molecular weight greater than 30,000. Its small bead size contributes to higher efficiency in these processes. Different types of Sephadex vary in terms of cross-linking, resulting in differences in swelling and molecular fractionation range. Sephadex G-50 is one of five G-types available, ranging from G-10 for small molecules to G-75 for larger molecules. Sephadex G-50 comes in four different particle sizes, such as Coarse, Medium, Fine, and Superfine.
