SW480 Cell Line Description and Applications Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > SW480 Transfection Reagent (Colon Adenocarcinoma, CCL228) SW480 Cell Line Description and Applications The SW480 cell line originates from a Dukes type B tumor from the colon of a 50-year old Caucasian male with colorectal adenocarcinoma. This cell line displays epithelial morphology and expresses an elevated level of p53 protein. The SW480 cell line also expresses a host of oncogenes including fos, H-ras, N-ras, sis, myb, c-myc, and K-ras. The cell line has a mutation in the 12 codon of the ras gene. The SW480 cell line has applications for research related to colon cancer therapeutics as well as in a wide array of biomedical research.

SW480 Transfection Protocol Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > SW480 Transfection Reagent (Colon Adenocarcinoma, CCL228) SW480 Transfection Protocol 1. Plate 10,000 - 15,000 SW480 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 SW480 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 SW480 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 > SW480 Transfection Reagent (Colon Adenocarcinoma, CCL228) Data Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into SW480 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).
