CHO Cell Line:
Production of recombinant protein therapeutics is considered one of the most innovative biotechnological advances and can be highly effective for treatment of many diseases and conditions, including cancers, genetic and autoimmune disorders, and infectious diseases. Various non-human mammalian cell lines are generally used for the production of therapeutic proteins, with Chinese hamster ovary (CHO) cell line being the most important because of its ability to perform human-like protein folding. The Chinese Hamster Ovary (CHO) tissue cell line was first established in 1957 using Chinese Hamster (Cricetulus griseus) ovary cells and is one of the most well-used cell lines for clinical research, and for the synthesis of therapeutic proteins. Also, this mammalian cell line is highly utilized in transfection as well as in large-scale recombinant protein production. CHO cells exhibit an epithelial-like cell morphology and are extensively employed in biomedical research and biotechnology R&D applications. Altogen Biosystems offers the lipid-mediated CHO transfection reagent kit for Chinese hamster ovary cells that yields nearly 90% transfection efficiency.
Figure 1. GAPD mRNA levels were quantified using real-time RT-PCR in the CHO cells transfected with siRNAs targeting GAPD or non-silencing siRNA. Forty-eight hours post-transfection, the cells were harvested and analyzed by real-time RT-PCR for GAPDH mRNA expression levels. Data were normalized against the 18S rRNA signal. Control samples were either mock-transfected or untreated. Values are normalized to untreated sample. Data are means ± SD (n=3).
Figure 2. Protein expression of GAPDH in CHO cells. DNA plasmid expressing GAPDH or siRNA targeting GAPDH were transfected into CHO cells following Altogen Biosystems transfection protocol. At 72 hours post-transfection the cells were analyzed by Western Blot for protein expression levels (normalized by total protein, 10 µg of total protein loaded per each well). Untreated cells used as a negative control.
