How can Product A50120, DEAE-Sephadex® resin be regenerated?
1 answer-
Regeneration is generally accomplished by washing with high ionic strength buffer or decreasing/increasing pH. The resin is then re-equilibrated in binding buffer.

What is the procedure for swelling Product A50120, DEAE-Sephadex® resin?
1 answer-
Weigh out the required amount of dry powder and suspend it in the buffer of choice. Although the swelling volume will be specific to the binding buffer used, generally 1 gram of powder will swell to 25 mL final volume of medium. Excess binding buffer should be used. Swell the resin for 1-2 days at room temperature or 2 hours at 100°C over boiling water. After swelling, wash the resin on a Buchner funnel with binding buffer. Prepare a slurry with 75% swelled medium/25% binding buffer.
