    摘要: The present invention relates to a method of expressing an immunotoxin in Pichia pastoris strain mutated to toxin resistance comprising a) growing the Pichia pastoris in a growth medium comprising an enzymatic digest of protein and yeast extract and maintaining a dissolved oxygen concentration at 40% and above; and b) performing methanol induction with a limited methanol feed of 0.5-0.75 ml/min/IO L of initial volume during induction along with a continuous infusion of yeast extract at a temperature below 17.5° C., antifoaming agent supplied up to 0.07%, agitation reduced to 400 RPM, and the induction phase extended out to 163 h.

    摘要: A reagent and the protocol for the treatment of Graft Versus Host Disease is disclosed. Monoclonal antibodies specific for T-lymphocytes in human donor bone marrow are covalently linked to separate ricin toxin, combined in a mixture to form a treatment reagent, and combined with bone marrow removed from a human donor. The bone marrow-reagent mixture is then infused into an irradiated recipient. This protocol virtually eliminates T-lymphocyte activity, the cause of Graft Versus Host Disease.
