Questions

1–5 of 5 Questions  
  1. How should I regenerate Product A25120, DEAE-Sephadex® A-25 chloride form?

    1 answer
    1. 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.
