General description

Sephadex G-50 Fine is a widely used gel filtration resin designed for desalting and buffer exchange of biomolecules with a molecular weight greater than 30,000. Its small bead size contributes to higher efficiency in these processes. Different types of Sephadex vary in terms of cross-linking, resulting in differences in swelling and molecular fractionation range. Sephadex G-50 is one of five G-types available, ranging from G-10 for small molecules to G-75 for larger molecules. Sephadex G-50 comes in four different particle sizes, such as Coarse, Medium, Fine, and Superfine.
Sephadex® G-50 is a gel filtration medium used in affinity chromatography, protein chromatography, and gel filtration chromatography. Sephadex is a beaded gel prepared by crosslinking dextran with epichlorohydrin.
Fractionation Range (MW)
Globular Proteins: 1,500 - 30,000
Dextrans: 500 - 10,000

Application

Sephadex® G-50 has been used:
  • to remove the non-entrapped carboxyfluorescein (CF) from the liposome suspension
  • in the purification of monoclonal antibody (mAb) humanized MN-14 by centrifuged size-exclusion chromatography
  • in desalting the recombinant enzymes eluted in the fraction five and six

Sephadex® G-50 is suitable for use in:

  • the separation of low and high molecular weight molecules
  • affinity chromatography, protein chromatography, and gel filtration chromatography

Features and Benefits

  • Desalts, removes contaminants, and transfers to a new buffer in one step.
  • Suitable for DNA purification from small molecules using gel filtration.
  • Features a small bead size, resulting in shorter diffusion distances.
  • Considered a classic gel filtration resin.

  • Desalting with Sephadex is considered superior to dialysis because it saves time, has a low dilution factor, and recovers high activity even with minute amounts of sample
