  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. How do I reconstitute Product D2189, [Glu52]-Diphtheria toxin from Corynebacterium diphtheriae?

    The vial can be reconstituted with 1.0 mL of sterile water. Each vial contains 1 mg of Diphtheria toxin CRM mutant, sodium phosphate buffer, and lactose. It can sometimes be hard to get the product into solution due to the lactose used as a stabilizer. The supplier suggests slight warming (to at least room temperature or 30 °C, but not more than 37 °C) followed by a brief vortex to break up the filaments.   

  4. What kind of mutant, is Product D2189, [Glu52]-Diphtheria toxin from Corynebacterium diphtheriae, and how is this product different from Product No. D0564?

    Product No. D0564 is the wild-type toxin and possesses enzymatic activity.  The Glu52 diptheria toxin, also known as CRM197, has a mutation in fragment A (a glycine to glutamic acid substitution at position 52) that results in the complete loss of enzymatic activity. More information on the mutant can be found in the following reference: Uchida, T., Pappenheimer, Jr., A.M. and Harper, A.A.,  J. Biol. Chem., 248, 3851-3854 (1973).

  5. What is the molecular weight of Product D2189, [Glu52]-Diphtheria toxin from Corynebacterium diphtheriae?

    On reducing SDS gels, this protein migrates as a single band of an approximate molecular weight of 63,000 Daltons.      

  6. What is the Department of Transportation shipping information for this product?
