GenJet™ In Vitro DNA Transfection Reagent for C6 Glioma Cells

GenJet™ DNA In Vitro Transfection Reagent for C6 Glioma cell is pre-optimized for transfecting C6 glioma cells . The C6 glioma cell line is a widely used cell line in neurobiological research. Compared to primary neural cells, the C6 cell line offers some major advantages like easy accessibility and culture as well as a good availability of high cell numbers. Nevertheless, the biggest disadvantage of the C6 cells is that they are difficult-to-transfect with commonly used non-viral transfection methods. The pre-optimized transfection reagent simplifies the transfection of C6 cells. Transfection efficiencies of over 60% can be easily achieved with excellent cell viabilities of above 90%.

Tips for selecting diluents for GenJet™ DNA transfection reagents.
For efficient formation of transfection complexes, it is essential to choose an appropriate diluent to dilute the DNA transfection reagent and DNA. In addition to temperature and incubation time, the nature of the diluent is very important for the complete formation of the transfection complex, thus significantly affecting the DNA transfection efficiency. According to our validation data, the appropriate diluent is 50 times more efficient than the "wrong" diluent.

Follow the following technical tips to choose the proper diluent for GenJet™ DNA transfection reagents:
1. For the complete formation of transfection complex, the diluent must be serum-free and protein free.
2. Try to use a diluent that is closest to the composition of cell culture medium. If you are using DMEM (supplemented with serum and antibiotics) to grow HEK293 cells, the best diluent is serum-free and antibiotics-free DMEM. If you are using RPMI-1640 Medium (supplemented with serum and antibiotics) to grow Hela cells, the best diluent is serum/antibiotic-free RPMI-1640 medium.
3. Do not use media containing unknown components. For example, never use Opti-MEM™ to dilute GenJet™ DNA transfection reagents. According to our validation data, diluting our transfection reagents and DNA with Opti-MEM™ at least sacrificed 50% transfection efficiency on HEK293, Hela, CHO and NIH 3T3 cells. In addition, Opti-MEM™ may contains low level of serum, which would greatly compromise transfection efficiency.
4. Basically serum-free DMEM with high glucose is pretty good choice. It is very easily accessible and compatible with other cell growth mediums. If you have trouble with lower transfection efficiency, you may think about changing diluent to serum-free DMEM with high glucose. If you do not know how to choose a proper diluent, you can try serum-free DMEM with high glucose first which usually gives you very good transfection efficiency.
