PARTICLES HAVING IMMUNOGENIC PROPERTIES OF THE HBS ANTIGEN AND CARRYING A FOREIGN ANTIGENIC SITE TO THE EPITOPES CARRIED BY THE HBS ANTIGEN, ANIMAL VECTORS AND CELLS FOR THE PRODUCTION OF SUCH PARTICLES AND COMPOSITIONS CONTAINING SUCH PARTICLES FOR THE PRODUCTION

摘要

THE INVENTION CONCERNS PARTICLES HAVING THE ESSENTIAL CHARACTERISTICS OF HBS ANTIGEN-BASED PARTICLES, SUCH PARTICLES CONSTITUTING FROM A MAJOR CHARACTERISTIC POLYPEPTIDE OF THE HBS ANTIGEN WHICH HAS BEEN INCORPORATED AS A SINGLE POLYPE SEPARATE FROM THOSE NORMALLY CARRIED BY THE GENE S 'AMINO ACIDS COMPRISES NOT MORE THAN 16 AMINO ACIDS, TO BE EXCRETED IN THE CULTURE MEDIUM OF THE SAID CELL LINE.
