FIELD: medicine.
SUBSTANCE: invention concerns genetic engineering, biotechnology, immunology and medicine and can be applied in obtaining antitumoral vaccine and melanoma treatment. Vaccine compositions are based on heat shock proteins and antigen peptides for treatment of tumor disease, the said compositions containing hybrid protein consisting of heat shock HSP70 family protein and one of specific melanoma MAGE peptides (A1, A2, A3) or gp 100, as well as suitable pharmaceutical carrier. The invention also claims a method for obtaining the said hybrid proteins by gene expression in synthetic recombinant vectors in producer strains of E coli BL21 (DE3) cells.
EFFECT: improved immunising power.
