Abstract��
Interleukin-11 (IL-11) is a kind of muti-function protein. Usually,people apply the thioredoxin fusion system containing the gene IL-11 to express IL-11 fusion protein in the E.coli and apply the immobilized metal affinity chromatography to purify the expression. In this paper,we study the affinity chromatography technics of the IL-11. The results show that both the purity and the rate of recovery reach the better level. It lays foundation for the followed purification.
