Hersteller:: United States Biological
Host:: Mouse
Immunogen:: Diphtheria toxoid.
Klon:: 1.B.234

Weitere Details:: Diphtheria Toxin catalyzes the ADP-ribosylation of eukaryotic aminoacyl-transferase II (EF-2) using NAD as a substrate. This reaction forms the basis for its toxicity toward eukaryotic organisms. The toxin is secreted as a single polypeptide chain of about 63kD, it is then processed to form A and B fragments both of which appear to be required for toxicity. Applications: Suitable for use in ELISA. Other applications have not been tested. Recommended Dilutions: Optimal dilution to be determined by the researcher. Hybridoma: Sp2/0 myeloma cells with spleen cells from Balb/c mice. Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
