GenJet™ DNA In Vitro Transfection Reagent for L929 cell is pre-optimized for transfecting L929 cells. L929 is a murine aneuploid fibrosarcoma cell line which is often used to assay TNF-alpha and TNF-beta. Treatment with TNF initiates apoptosis and subsequent cell death.  The level of detection is on the order of 50 pg/mL. Another cell line which is approximately 5-10-fold more sensitive is WEHI-164. Some L929 subclones have been developed that allow detection of TNF at concentrations of approximately 30 pmol/L (approximately 500 fg/mL). Sublines that are resistant to TNF have been established also.

Refer to the following optimal transfection conditions for maximal transfection efficiency on L929 cells. GenJet™ reagent, 1.0 ml, is sufficient for 300 to 600 transfections in 24 well plates or 150 to 300 transfections in 6 well plates.
