Sephadex G-100 is useful for desalting and buffer exchange of very large biomolecules.

• Quickly desalts, removes contaminants and transfers to a new buffer in a single step
• Classic gel filtration medium

Sephadex is a gel filtration medium 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-100 is one of six different G-types ranging from G-10 for small molecules to G-100 for very large biomolecules.

Sephadex G-100 Superfine is designed for specific cases requiring very high resolution.
