RECOMBINANT HUMAN INTERLEUKIN 2 AND PRODUCTION THEREOF

摘要

PURPOSE:To produce a recombinant interleukin 2 without containing other human-derived proteins, by cultivating a transformant transformed with a vector containing a gene capable of coding human interleukin 2 in a culture medium. CONSTITUTION:A transformant containing a vector containing a gene capable of coding human interleukin 2 is cultivated in a culture medium to produce a recombinant human interleukin 2 substantially without containing other human- derived proteins. A vector containing a gene capable of coding interleukin 2 containing an amino acid sequence expressed by formula I in the molecule is cultivated in a culture medium to produce a recombinant human interleukin 2 containing an amino acid sequence expressed by formula I substantially without containing other human-derived proteins.
