  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 is the procedure for swelling Product A50120, DEAE-Sephadex® resin?

    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.

  4. What procedures are used for elution when using Product A50120, DEAE-Sephadex® resin?

    For DEAE Sephadex, elution is achieved using either an increasing salt gradient or a decreasing pH gradient.

  5. How can Product A50120, DEAE-Sephadex® resin be regenerated?

    Regeneration is generally accomplished by washing with high ionic strength buffer or decreasing/increasing pH. The resin is then re-equilibrated in binding buffer.

  6. How can Product A50120, DEAE-Sephadex® resin, be stored?

    Store swollen medium refrigerated in the presence of a preservative such as 20% Ethanol. Sodium azide or thimerosal should not be used.
