GE amersham SEPHADEX G-50 葡聚糖凝膠G-50填料

Sephadex G-50 Coarse is well established gel filtration medium for desalting and buffer exchange of biomolecules >30 000 molecular weight. The larger bead size of Coarse is suitable for large scale separations .

• Quickly desalts, removes contaminants and transfers to a new buffer in a single step.
• Suitable for purification of DNA from small molecules by gel filtration
• Larger bead size for large scale group separations where high flow rates and low operating pressures are required.
• Largest bead size in the Sephadex G-50 range.

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-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. Coarse and Medium are are preferred for large scale group separations where high flow rates and low operating pressures are required.
