Abstract:Objective: High cell density and high expression culture of recombinant E. coli TG1/pGEX hCT to produce recombinant human calcitonin(hCT). Methods and Results: Batch and fed batch culture were used with the carbon nitrogen control, DO stat method in 5 L NBS BioFlo 3000 type autocontrol fermentor was carried out to produce recombinant hCT in E.coli TG1/pGEX hCT. The final cell density and concentration of GST hCT fusion protein were 58.6 D (600) and 3.2 g/L. Conclusion: This study provides a basic work for production recombinant hCT in industrial scale.
Keywords:calcitonin  expression
