Gene coding for interleukin-2 polypeptide, recombinant DNA carrying said gene, cell lines possessing the recombinant DNA,and method for producing interleukin-2 using said cells

摘要

A gene coded for a polypeptide which possesses interleukin-2 activity is isolated, and connected with a vector DNA which is capable of replicating in a procaryotic or eucaryotic cell at a position downstream of a promoter gene in the vector obtaining a recombinant DNA, with which the cell is transformed to produce interleukin-2.
