CHO-K1 Cells

CHO-K1 cells are a subline derived from the CHO cell line, which was originally established in the early 1950s from a Chinese hamster ovary. CHO-K1 cells are widely utilized in the production of therapeutic monoclonal antibodies and other biopharmaceuticals. Their extensive use in biopharmaceutical protein production and vaccines is attributed to their eukaryotic nature, which allows for proper folding, assembly, and post-translational modifications such as glycosylation, which influences the stability, efficacy, and safety of the produced proteins. In the realm of recombinant protein production, the CHO-K1 cell line is used to express a wide array of proteins, including monoclonal antibodies, growth factors, cytokines, and enzymes. These proteins have applications in therapeutic treatments, diagnostic assays, and vaccine formulations. CHO-K1 cells exhibit a robust growth rate and are adaptable to various culture conditions, including suspension and adherent cultures, making them highly valuable for large-scale bioproduction processes. They possess a high level of genetic stability and are used for stable cell line development as they are capable of amplifying and expressing exogenous genes efficiently, which is critical for producing high yields of recombinant proteins. CHO-K1 chinese hamster cells can be easily transfected with a variety of vectors for gene expression, facillitating gene editing or knockdown. This flexibility allows researchers to introduce specific genes, silence genes, or even perform targeted gene editing using technologies like CRISPR-Cas9 in CHO-K1 host cells. In conclusion, the chinese hamster CHO-K1 cells and CHO cells are pivotal in biotechnological research and biopharmaceutical production, offering a versatile platform for the study of gene function and the large-scale production of recombinant proteins.
