Inducing expression of hepatitis-B virus cytomembrane small-protein and middle-protein gene in clover

This invention relates to the hepatitis B virus involucrum small protein and the protein gene simultaneously carries on the inductivity expression in the transgene alfalfa the method and the application. The above two antigen protein gene is put in the alfalfa nitrous acid reductases gene to start separately under the sub-control, under the normal growth condition, these two extraneous source protein gene is at the silence condition, does not have any goal protein production. But under the nitrate induction, the nitrous acid reductases gene starts sub-is activated, and regulates the hepatitis B virus involucrum small protein afterward and the protein gene simultaneously carries on the highly effective expression and the accumulation in alfalfa in vivo. The human or other mammals contain this two reshuffles through direct consumption to fight the genetically engineered lucerne of original egg white , or through enteron aisle the way use to medicine divides from these genetically engineered lucerne central sections or complete purification makes Yi Xing in hepatitis virus membrane little egg white and egg white may so arouse person or other mammals as the major active composition of capsule, mixture or other preparation for Yi Gan virus coating fights the immunity of original egg white to reply reaction.
