High Density CHO-K1 cells Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > CHO-K1 Transfection Reagent (Ovarian Adenocarcinoma) CHO-K1 Cell Line Description and Applications The CHO-K1 cell line originates from a subclone of the CHO cell line, a cell line established in 1957 and derived from the ovarian tissue of an adult Chinese hamster (Cricetulus griseus). The CHO-K1 cell line actually requires proline for cell growth, but nonetheless makes an excellent transfection host. The cell line is resistant to poliovirus 2, Modoc virus and Button Willow virus. The CHO-K1 cell line was mutagenized with ethyl methane sulfonate and this generated a cell line lacking DHFR.

CHO-K1 Transfection Protocol Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > CHO-K1 Transfection Reagent (Ovarian Adenocarcinoma) CHO-K1 Transfection Protocol 1. Plate 10,000 - 15,000 CHO-K1 cells per well in 0.5 ml of complete growth medium 12–24 hours prior to transfection 2. Wash with 1xPBS and add 0.5 ml of fresh growth medium 3. Prepare transfection complexes by mixing 40 µl of serum-free medium, 5.5 µl of transfection reagent, and • 750 ng DNA (or mRNA), or • 30 nM - 50 nM of siRNA (or microRNA) *Referred to a final volume including growth medium 4. Incubate transfection complexes at RT for 15 - 30 minutes 5. Optional: Add 2 µl of Complex Condenser. This reagent reduces the size of transfection complex, therefore increasing transfection efficiency; however it may increase cell toxicity 6. Add prepared transfection complexes to 0.5 ml of complete growth medium with CHO-K1 cells (from step 2) 7. Incubate cells at 37ºC in a humidified CO2 incubator 8. Assay for phenotype or target gene expression 48 - 72 hours after transfection Optional: Transfection efficiency can be increased by addition of Transfection Enhancer reagent. Add 2 µl of Transfection Enhancer reagent 12-24 hours after transfection If the viability of CHO-K1 cells being transfected is affected at 16 - 24 hours post-transfection, the level of cytotoxicity can be decreased by changing the growth medium and eliminating redundant exposure of cells to transfectant Altogen Biosystems  848 Rainbow Blvd #823  Las Vegas  NV  89107  USA Telephone  702 349 6103  Fax  702 989-0841  email  techserv@altogen.com

Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > CHO-K1 Transfection Reagent (Ovarian Adenocarcinoma) Data Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into CHO-K1 cells following the recommended protocol. At 48 hours post-transfection the cells were analyzed by qRT-PCR for Lamin A/C gene expression levels. 18S rRNA levels were used to normalize the Lamin A/C data. Values are normalized to untreated sample. Data are means ± SD (n=4).
