ABSTRACT
Objective Construction of human IL‐4 recombinant expression vector and then conduct the expression ,purification and identification of human recombinant IL‐4 .Methods the open reading frame of IL‐4 was amplified by nest PCR with total RNA from PBMC of healthy volunteer .And then the amplified IL‐4 was inserted into pET101/D‐TOPO ,transformed into BL21 ,ex‐pressed ,purified and indentified .Results The size of amplified open reading frame of IL‐4 was about 460 bp and the sequence was correct .After transformed into BL21 ,the IL‐4 clone with higher expression level was selected by selection of different clones insert‐ed with IL‐4 and the size of expressed ,purified IL‐4 was about 28 × 103 .Western blot results showed that the size of single band was identical with the expected protein .Conclusion Human IL‐4 recombinant protein was got successfully .
