Diphtheria Toxin for Cell Ablation

April 25, 2016


By: Karen Crawford, Ph.D., President

In 1983, List Labs introduced Diphtheria Toxin to the research community. Researchers have purchased Diphtheria Toxin for various uses. One common use is cell ablation. The receptor for Diphtheria Toxin is also called heparin-binding EGF-like growth factor (HB-EGF). This receptor, located on several cell types, binds Diphtheria Toxin, allowing the toxin to enter and kill these cells. Transgenic mice have been developed to express the diphtheria toxin receptor on dendritic cells allowing their depletion. Diphtheria Toxin, Unnicked, from Corynebacterium diphtheriae (Product #150) is an active native enzyme, a useful tool for your research.
