GenJet™ Plus DNA In Vitro Transfection Reagent

GenJet™ Plus DNA In Vitro Transfection Reagent is enhanced version of GenJet™ DNA In Vitro Transfection Reagent. GenJet™ Plus is formulated by addition of a booster peptide, giving rise to up to 20 times higher efficiency on variety of mammalian cells in comparison of its previous version. GenJet™ Plus was shown to efficiently deliver genes to various established cell lines as well as primary cells including HEK293, 293T, 293E, CHO, COS1, HeLa, NIH 3T3, insect cell lines (Sf9 and Sf21) and a variety of other eucaryotic cell lines with less toxicity. GenJet™ Plus reagent, 1.0 ml, is sufficient for 667 transfections in 24 well plates or 333 transfections in 6 well plates.

Features compared with old version GenJet™ In Vitro DNA Transfection Reagent
- Cell-dependent 3~20 times higher efficiency
- Top choice for hard-to-transfect cells
- Equally good for very long DNAs (up to 46 kb)
- Efficiency boosted in the presence of serum and antibiotics for most of cell types
- Exceptional high levels of recombinant protein production

Background

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.
