There are many differences in the applicable production cells of different viruses in the project. For example, the applicable production cells of oncolytic virus usually vary with the strain of virus and the content of genetic modification, mainly in the aspects of virus yield and activity, so it is necessary to screen the applicable production cells and adaptive technology. In addition, when the suspension cell production process is adopted, and the existing suspension cell lines can not meet the production requirements, it is necessary to screen and domesticate the cells to obtain better production efficiency and ensure the safety of the cell matrix for production. We have experience in screening production cells of various viruses and domestication of various cells, and can provide you with screening and domestication services for cell lines.
