Abstract:
Vasostatin has previously been expressed in fused form or in inclusion body form in Escherichia coli. Here the protein was expressed in soluble non-fusion form in BL21(DE3)pLysS by IPTG induction. The expression level of vasostatin was about 15% of the total cellular protein. The expressed vasostatin was purified and its biological activity was investigated by an endothelial cell proliferation assay.
