NIH3T3 Cell Line Description and Applications Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > NIH3T3 Transfection Reagent (Swiss Mouse Fibroblasts) NIH3T3 Cell Line Description and Applications The NIH3T3 cell line was established in 1962 by researchers at the New York University School of Medicine. It was derived from cells taken from a Swiss mouse embryo. The 3T3 cell line is a type of murine fibroblast cell and is now the classic fibroblast cell line in research. Furthermore, the cell line can be used as “feeder cells” for research related and maintenance of undifferentiated human embryonic stem cells. Murine embryonic fibroblasts, and in particular the 3T3 cell line can be used to secrete growth factors to cultivate keratinocytes. Research indicates that NIH3T3 cells are susceptible to the leukemia and sarcoma viruses and that benzodiazepines inhibit growth of this cell line. The 3T3 cell line is an excellent transfection host and is also useful for titration studies related to mouse viruses.

NIH3T3 Transfection Protocol Leading Developer and Manufacturer of In Vivo and DNA Transfection Kits, Transfection Reagents and Electroporation Delivery Products Products > NIH3T3 Transfection Reagent (Swiss Mouse Fibroblasts) NIH3T3 Transfection Protocol 1. Plate 10,000 - 15,000 NIH3T3 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 NIH3T3 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 NIH3T3 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 > NIH3T3 Transfection Reagent (Swiss Mouse Fibroblasts) Data Figure 1. GAPD mRNA levels were quantified using real-time RT-PCR in NIH3T3 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).

Protein expression of GAPDH in NIH3T3 cells. DNA plasmid expressing GAPDH or siRNA targeting GAPDH were transfected into NIH3T3 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.
