摘要

Annexin B1 has been cloned in Escherichia coli (E. coli) K802 in previous works. After temperature shift induction the protein was expressed as soluble form. Then a separation method for annexin B1 from E. coli cells by ion-exchange chromatography has been developed and validated. The method exhibited a good reproducibility and is easy to operate. It has shown that annexin B1 isolated by chromatography had high anticoagulant activity.
