In Vitro DNA Transfection Reagents:

Based on our unique and proprietary “VIPs” and polymer synthesis technologies, currently we are developing and manufacturing three categories of DNA/siRNA transfection reagents, which show distinct transfection characteristics compared with the leading products in the market. What's more important is that the transfection reagents we are manufacturing are very affordable and will save your precious research budget.

Description
OKDNAfect DNA In Vitro Tranfection Reagent is a powerful transfection reagent that ensures effective and reproducible transfection with invisible toxicity. GenJet™ is formulated by unique chemistry (covalently cross-linking cationic lipids with polymer), giving rise to exceptional transfection efficiency with distinguishable features in comparison of other types of reagents. GenJet™ was shown to 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. GenJet™ reagent, 1.0 ml, is sufficient for 300 to 600 transfections in 24 well plates or 50 to 100 transfections in 6 well plates.

Application
- Deliver DNA/RNA into mammalian, insect cells
- Greatly enhance (up to 200 times higher efficiency) virus (e.g., replication-deficient Adenovirus) infection of hard-to-transfect cells

Features
- Exceptional high titers of virus production
- Equally good for very long DNAs (up to 56 kb)
- Equally good for single or multiple DNA transfections
- Exceptional high levels of recombinant protein production
- Top choice for hard-to-transfect cells 
- Inexpensive transfection reagent 

Storage Condition
Store at 4 °C. If stored properly, the product is stable for 12 months or longer.

Comparisons of Transfection Efficiency and Cytotoxicity of OKDNAfect Transfection Reagent with the Leading Brand Name Products

Exceptional transfection efficiency of extremely long DNA by OKDNAfect Transfection Reagent. HEK293 cells were transfected with GFP tagged DNA (total 14 kb) by OKDNAfect (upper panel) and FuGene™ 6 (lower panel) respectively. The cells were visualized by Nikon Eclipse Fluorescence microscope with DIC phase (left panel) and FITC (right panel) imaging 24 hours post transfection


Exceptional high titers of lentivirus generated from 293F cells. Three DNAs co-transfected with GenJet™ In Vitro DNA Transfection Reagent (left panel) in comparison of LipoFectamine 2000™ (L2K, right panel). 100 microliter virus supernatant from 293F cells were used to counter-infected 293F cells which was then passed FACS. The numbers at the upper right corner indicate the percentage of transduced cells. The titers of lentivirus generated with OKDNAfect and L2K were quantified to be 7.9x10⁶ and 3.1x10⁶ tu/ml respectively



Primary Murine Skin Fibroblast transfected with pEGFP-C1 plasmid using OKDNAfect Transfection Reagent (upper panel) and the most popular brand product FuGene™ HD (lower panel). The cells were visualized by Nikon Eclipse Fluorescence microscope with DIC phase imaging (left panel) and FITC imaging (right panel) 24 hours post-transfection



Primary Murine Keratinocytes transfected with pEGFP-C1 plasmid using OKDNAfect Transfection Reagent (upper panel) and one of the most popular brand product FuGene™ HD (lower panel). The cells were visualized by Nikon Eclipse Fluorescence microscope with DIC phase imaging (left panel) and FITC imaging (right panel) 24 hours post-transfection


Comparison of cytotoxicity of OKDNAfect Transfection Reagent with L2K™ on primary murine skin fibroblast. The primary murine fibroblast was incubated with the indicated transfection reagents/pEGFP-C1 (DNA) complexes above for 4 hours in serum-free DMEM High Glucose medium followed by replacement of complete serum-containing medium. The cells were visualized by Nikon Eclipse Fluorescence microscope with DIC phase imaging 24 hours post transfection
