What type of cells are CHO?
Chinese hamster ovary (CHO) cells are an epithelial cell line derived from the ovary of the Chinese hamster, often used in biological and medical research and commercially in the production of recombinant therapeutic proteins.
What are GS CHO cells?
The CHO-GS cell line is the prevalent protein expression system worldwide for therapeutic antibodies. CHO cell protein production laboratories are predominantly using serum-free CHO media.
Why do we use CHO-K1 cells?
The Advantages of CHO Cells Grow well in suspension and as adherent culture, rendering the cells ideal for GMP procedures. Their tolerance to variations in pH, oxygen levels, temperature or pressure make them the ideal cell for large-scale culture. High recombinant protein yields and specific productivity.
Why are CHO-K1 cells useful?
The Advantages of CHO Cells Their tolerance to variations in pH, oxygen levels, temperature or pressure make them the ideal cell for large-scale culture. High recombinant protein yields and specific productivity. Thanks to genetic optimization, protein yields of 3-10 grams per liter of cell culture.
How do CHO cells produce antibodies?
Establishing stable Chinese Hamster Ovary (CHO) cells producing monoclonal antibodies (mAbs) usually pass through the random integration of vectors to the cell genome, which is sensitive to gene silencing. One approach to overcome this issue is to target a highly transcribed region in the genome.
What proteins do CHO cells produce?
In particular, CHO cells are used to produce recombinant therapeutic proteins and monoclonal antibodies (mAbs), such as adalimumab, bezlotoxumab, avelumab, dupilumab, durvalumab, ocrelizumab, and brodalumab (Kaneyoshi et al., 2019a; Henry et al., 2020).
What is the origin of CHO K1 cells?
The CHO-K1 cell line was derived as a subclone from the parental CHO cell line initiated from a biopsy of an ovary of an adult Chinese hamster by T. T. Puck in 1957. The cells require proline in the medium for growth.
Is CHO-K1 cell line suitable as a transfection host?
This cell line is suitable as a transfection host. The CHO-K1 cell line was derived as a subclone from the parental CHO cell line initiated from a biopsy of an ovary of an adult Chinese hamster by T. T. Puck in 1957. Chromosome Frequency Distribution 50 Cells: 2n = 22. Stemline number is hypodiploid.
What is chocho-k1sv?
CHO-K1SV is a suspensio … Optimization of cell line development in the GS-CHO expression system using a high-throughput, single cell-based clone selection system J Biosci Bioeng. 2015 Sep;120(3):323-9.doi: 10.1016/j.jbiosc.2015.01.002. Epub 2015 Mar 17. Authors Tsuyoshi Nakamura 1 , Takeshi Omasa 2
