When Tse Wen Chang and Nancy T. Chang were setting up Tanox, Inc. in Houston, Texas in 1986, they purchased the rights on the antibody matrix patents from Centocor as part of the technology base to build their new startup.
Tanox, a biotech company based in Houston, Texas, proposed in 1987 that by targeting membrane-bound IgE (mIgE) on B lymphoblast and memory B cells, those cells can be lysed or down-regulated, thus achieving the inhibition of the production of antigen-specific IgE and hence a shift of immune balance toward non-IgE mechanisms.
