摘要:
Interleukin 2 of human cell origin, which has a specific activity of more than 2 x 10 5 units/mg protein and is free from other human lymphokines and monokines is a useful immunoprophylactic and immunotherapeutic agent per se or in combination with other chemotherapeutic agents and/or other immunotherapeutic agents.
摘要:
Interleukin-2 polypeptides, which are free from substances produced by human cells, are provided. These interleukin-2 polypeptides are produced by a culture of cells of Escherichia coli, constructed by gene-recombination technique, into which a plasmid comprising the genetic information for the synthesis of human IL-2, has been inserted.
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.
