Description

Description

Sephadex is a gel filtration medium prepared by crosslinking dextran with epichlorohydrin. Its larger bead size is well-suited for large scale separations, where high flow rates and low operating pressures are required.
  • 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
  • Classic gel filtration medium
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 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).
