Our technologies

Using Escherichia coli expression system to produce protein has been recognized as fast and low cost method. Although the produced protein lacks post-translational modifications that affect the protein structure, It has no effect on vaccine antigens that induce immune responses with short peptides (epitopes).

 In addition to vaccine antigen designs, we are proficient in recombinant DNA technology, E. coli fermentation , protein purification and refolding, and protein freeze-drying technology.

We also accept customized cases or cooperation projects such as gene selection, protein fermentation production, and vaccine antigen development.
