    摘要: A method is provided for refolding and purifying biologically active human interleukin-4 from insoluble aggregates in bacteria. The method comprises solubilizing the aggregates with an aqueous solution containing a chaotropic agent and a reducing agent, followed by steps of controlled and sequential reduction in the concentrations of the two agents to form biologically active human interleukin-4. Finally the biologically active human interleukin-4 is separated from inactive material by standard biochemical procedures.
