Abstract
A method for production of a Varicella Zoster Virus surface protein antigen is disclosed. The method for production of a Varicella Zoster Virus surface protein antigen is an effective production method capable of obtaining the Varicella Zoster Virus surface protein antigen in high yield and high purity. Therefore, the method is useful for production of the Varicella Zoster Virus surface protein antigen for use as a vaccine composition for preventing or treating varicella or herpes zoster.
Claims15
A method for producing Varicella Zoster Virus (VZV) surface protein (gE) antigens, comprising steps of:
- (a) culturing a recombinant cell line prepared using Chinese hamster ovary (CHO) cell that produces the VZV gE antigens, to obtain a culture solution;
- and
- (b) purifying the culture solution,
- wherein the culturing step (a) comprises steps of:
- (a-1) performing seed culture on the recombinant cell line;
- and
- (a-2) performing production culture on the cell line that has undergone the seed culture, wherein the step (a-2) comprises culturing the cell line at a temperature of 34° C. to 35.5° C., and
- wherein the purifying step (b) comprises steps of:
- (b-1) performing anion exchange chromatography;
- (b-2) performing hydrophobic interaction chromatography, comprising adding sodium chloride to an eluate obtained through the anion exchange chromatography and loading it onto a hydrophobic interaction chromatography column, and washing with a washing buffer containing sodium chloride;
- (b-3) subjecting the culture solution to treatment with a virus-inactivating agent, to inactivate viruses, and then performing concentration and diafiltration;
- (b-4) performing mixed-mode chromatography, to obtain an eluate;
- and
- (b-5) subjecting the eluate to concentration and diafiltration, and then performing nanofiltration, the steps being performed in a series of sequences.
