Application
DEAE-Sephadex® A-25 has been used:
- to form DEAE-Sephadex A-25 (formate form) for glucosinolates (GLS) extraction using horseradish plants
- in the estimation of GLS content in Chinese kale sprouts
- production and purification of endozepine from astrocytes
- to identify and label an insulin-activated nitric oxide synthase inhibitor (protein) in acute myocardial infarction (AMI) patients
Features and Benefits
- Weak anion exchanger
- Suitable for batch techniques
- High binding capacities
- Non-reactive to commonly used aqueous buffers additives such as 8 M urea and 6 M guanidine hydrochloride

How should I regenerate Product A25120, DEAE-Sephadex® A-25 chloride form?
1 answer-
After each separation, elute any reversibly bound material either with a high ionic strength solution (e.g. 1 M NaCl in buffer) or by increasing pH. Regenerate the media by washing with at least 5 bed volumes of buffer, or until the column effluent shows stable conductivity and pH values.
