The specific concentration of non-ionic detergent for cleaning Sephadex Media is not explicitly mentioned in the available data. However, various sources suggest concentrations ranging from 0.1 – 0.5%. This information has not been validated. The general cleaning recommendations are as follows:
1. Wash with two column volumes of 0.2 M NaOH or a solution of a nonionic detergent. Washing the more porous Sephadex types (G-50 – G-200) with NaOH should be done outside the column because the gel will swell.
2. Re-equilibrate the gel with 2–3 column volumes of buffer before your next experiment. When necessary, the gel can be removed from the column and sterilized by autoclaving at 120 °C, pH 7.

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.

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[1]
- in the purification of monoclonal antibody (mAb) humanized MN-14 by centrifuged size-exclusion chromatography[2]
- in desalting the recombinant enzymes eluted in the fraction five and six[3]
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

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

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