RECOMBINANT DNA BODY CONTAINING GENE CODING POLYPEPTIDE HAVING HUMAN INTERLEUKIN-2 AND PROCARYOTE CELL TRANSFORMED BY THE SAME RECOMBINANT DNA BODY

摘要

PURPOSE:To obtain a gene useful for mass production of human interleukin-2 coding polypeptide having human interleukin-2 activity, containing special amino acid sequence. CONSTITUTION:A recombinant DNA is prepared by using gene coding polypeptide having human interleukin-2 activity, containing amino acid sequence expressed by the formula and a procaryote, preferably Escherichia coli is transformed by said recombinant DNA, then cultured to produce human interleukin-2.
