The Chinese hamster ovary (CHO) cell lines, stemming from the epithelial cells of the ovary of the Chinese hamster, are renowned for their immortality and frequent utilization in both biological and medical research. Additionally, they are commercially significant in the production of recombinant therapeutic proteins.
CHO cells are highly favored in the manufacturing of recombinant monoclonal antibodies, stemming from their proficiency in executing post-translational alterations on the antibody molecules. This process leads to enhanced stability and effectiveness of the antibodies, making them more reliable for therapeutic applications. nb cell
Overview - CHO-S Versus CHO-K1
Derived from the Chinese Hamster Ovary (CHO) epithelial cells, CHO-S and CHO-K1 cell lines are significant for numerous research endeavors, spanning both medical and biological domains. CHO-S is characterized as a suspension cell line, whereas CHO-K1 can exist as either a suspension or an adherent cell line.
The CHO cell growth thrives best at a temperature approximating 37oC.
Similar to the majority of mammalian cells, the CHO cells' preferred temperature for growth hovers around 37oC. While a reduction in culture temperature below 37oC leads to a decline in the specific growth rate (µ), it surprisingly sustains a higher viability for an extended duration [5-7, 9].
The Chinese Hamster Ovary (CHO) cells serve as the primary source for the manufacturing of contemporary biopharmaceuticals. Despite their vital role, these cells are immortalized and possess a significant tendency for genetic alterations. 28th of May, 2021
Despite their advantages, CHO cell-based expression systems encounter a few challenges: notably, a considerably steep cost of materials; a risk of transmitting infectious entities, including viruses and prions; a prolonged developmental phase from genetic modification to the establishment of a production cell line; and a limitation in effectively regulating N-glycosylation.
The Chinese Hamster Ovary (CHO) cell line holds significant importance in the realm of bioprocessing and pharmaceutical R&D. These cells exhibit robust growth in culture conditions and possess the capability to yield a diverse array of recombinant glycoproteins at elevated levels, making them a viable choice for large-scale production.
CHO cells remain a favored option for the manufacturing of numerous therapeutic proteins within the realm of mammalian cell cultures. Nevertheless, these cells are accompanied by certain drawbacks such as suboptimal productivity, stability concerns between the substrate and the product, a slower proliferation rate, and a relatively low cellular density.cho-k1 cells
CHO emerges as a preferred choice for both fleeting and enduring expression techniques, primarily due to its enhanced safety profile. Notably, the utilization of HEK293 cell lines and their derivatives in protein production poses significant health risks to humans, making CHO a more viable alternative.
