Transfection Reagent for SW480 Cells (Colon Adenocarcinoma Cells, CCL-228)
- A biodegradable polymer based transfection agent – once inside the cell, the polymer degrades into smaller less toxic components reducing cell toxicity, facilitating release of the transgene, and improving transfection efficiency
Effective transfection under conditions of up to 40% serum
Gentle enough to be used for single cell analysis

SW480 Cell Line:
Colorectal cancer is the second primary cause of cancer-related deaths in men, accounting for nearly 50,000 fatalities annually in the United States, as per the American Cancer Society (ACS). Colorectal cancer cell lines are extensively employed in preclinical colon cancer research and represent accurate molecular models of primary carcinomas. The SW480 cell line was established from a Dukes type B tumor in the colon of a 50-year-old Caucasian male patient with colorectal adenocarcinoma. The cells exhibit an epithelial morphology, and are susceptible to human immunodeficiency virus 1. Also, The SW480 cell line is negative for colon antigen 3 and colon-specific antigen-p and produces granulocyte-macrophage colony-stimulating factor. This cell line is positive for keratin by immunoperoxidase staining. SW480 display elevated levels of p53 protein, and positively expresses c-myc, K-ras, H-ras, N-ras, sis, myb, and fos oncogenes. SW480 cells have a mutation in the 12 codon of the ras p.o.gene, and therefore can be used in PCR assays of mutation for this codon. This cell line is widely used in biomedical research related to the search for treatments for colon cancer. Altogen Biosystems provides polymer-based transfection kits for the SW480 cell line.
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).
Figure 2. Protein expression of Lamin A/C in SW480 cells. DNA plasmid expressing Lamin A/C or siRNA targeting Lamin A/C were transfected into SW480 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.
