2.Expression and Purification of the Fusion Proteins hCGβ-(CTP)_4 and hCGβ-(CTP)_4-(C3d-P28)_4 in E.coli
3.Objective:To investigate the prokaryotic expression of the genes encoding proteins hCGβ- (CTP)_4 and hCGβ-(CTP)_4-(C3d-P28)_4 and to purify the recombinant proteins.
4.Conclusion:The recombinant proteins were successfully expressed in BL21(DE3)and purified. This study provides necessary data for further investigation of the immunogenicity and anti-cancer vaccine of fusion protein hCGβ-(CTP)_4-(C3d-P28)_4.
