RECOMBINANT PROTEINS WITH THE IMMUNE-REACTIVITY OF ANTIGEN AND HEPATITIS B VIRUS (HBEAG) PROCESS FOR PREPARING AND USING IN IMMUNOLOGICAL TESTS AND VACCINES

摘要

Recombinant yeast expression vectors with the features indicated in the claims are described. These recombinant yeast expression vectors can be used to produce HBeAg in yeast host organisms. Corresponding expression systems, transformed host organisms, diagnostic aids and pharmaceutical compositions are also described.
