Sephadex G-50 manufactured by Cytiva is a well established gel filtration resin for purification of DNA from small molecules. Sephadex G-50 is prepared by crosslinking dextran with epichlorohydrin. Sephadex G-50 is one of five different G-types ranging from G-10 for small molecules to G-75 for larger molecules. Sephadex G-50 is available in 4 different particle sizes (Coarse, Medium, Fine & Superfine) and Superfine has the smallest bead size for higher efficiency with shorter diffusion distances.
