Sephadex G-75 is well established gel filtration medium for desalting and buffer exchange of large biomolecules >80 000 molecular weight.

• Quickly desalts, removes contaminants and transfers to a new buffer in a single step.
• Suitable for buffer exchange and cleanup of large biomolecules, >80000 molecular weight
• Classic gel filtration medium

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.
