[Fusion expression of SLT-IIeB gene and FedF gene of Ee in Escherichia coli and its immunogenicity].

Abstract excerpt

The DNA fragment encoding the truncated SLT-IIeB and FedF of Ee strain were fused to the downstream of glutathione S-transferase (GST) of pGEX-KG expression vector, resulting in the fusion expression plasmid pKSF. After transformed into E. coli BL21 (DE3) and induced by IPTG, the results of SDS-PAGE showed that the GST-SF fusion protein was expressed in high level. Western blot was performed to confirm that the...
