Abstract
A gene coded for a polypeptide which possesses interleukin-2 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.
