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

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

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What does "G-50" mean in Sephadex®  G-50, Product G5080?

    "G" stands for gel.  "50" refers to the water regain of the gel, in this instance, 5.0 g water per g dry gel.

  4. What is the best buffer to use with Sephadex®  G-50, Product G5080?

    Sephadex® G-50 is very flexible in the buffers that can be used with it.  Essentially any common aqueous buffer can be used with Sephadex® G-50.  It is advised to filter buffers through a 0.22 micron filter before use.

  5. How stable is Sephadex® G-50, Product G5080, after swelling?

    Sephadex® is stable in water, salt solutions, organic and denaturing solvents.  If necessary, the gel can be removed from the column and sterilized by autoclaving at 120 deg C, pH 7. The pH stability is limited to low strengths and short times at extremes of pH 2-10, particularly in the acid range.  After any washes using solutions at extremes of acidic or basic pH, the Sephadex®  should be washed and reequilibrated with buffer at neutral pH as promptly as possible.

  6. How can I clean the Sephadex®  G-50, Product G5080, after use?

    To clean the gel, you can wash the gel with 2 column volumes (CV) of 0.2 M NaOH, outside of the column because the gel will swell in basic pH, or in a solution of non-ionic detergent.  Then you can rinse with water and re-equilibrate with 2-3 CV of buffer. If the resin is to be stored (longer than ~24 hours), equilibrate the resin with buffer containing an antimicrobial such as 20% ethanol or 0.02% sodium azide.

  7. What kind of separation can I expect from Sephadex®  G-50, Product G5080?

    As a general rule of thumb, Sephadex® G-50 is appropriate for the separation of molecules of ~30 kDa from molecules ~1.5 kDa
