Rapid and easy clone selection is possible! The negative test for exogenous factors has been conducted, and cell banking has been performed under cGMP conditions.
The "CHOZN Elite Cell Line" is a CHO (Chinese Hamster Ovary) mammalian cell expression system that proliferates in a suspension culture using a chemically defined medium free of animal-derived components. It is a subclone of the CHOZN GS KO cell line, achieving performance that surpasses the parent strain in various performance indicators such as efficiency of cell line development (CLD), predictable growth, and protein production levels. A technical user guide detailing the procedures for optimizing performance will be provided along with the cell line. **Features** - High-producing clones with titers of 7 to 13 g/L can be obtained through the introduction of standard vectors, resulting in cost reduction. - Easy to adopt and can be directly integrated into the customer's existing CLD processes, compatible with both fed-batch and perfusion processes. *For more details, please download the PDF or feel free to contact us.*
