Description
Based on our proprietary polymer synthesis  technology, PolyJet™ DNA In Vitro Transfection  Reagent is formulated as a biodegradable polymer based DNA transfection reagent that  ensures effective and reproducible transfection on HEK293, COS-7, NIH-3T3, HeLa,  CHO and a broad ranges of hard-to-transfect  mammalian cells. PolyJet™ reagent is able to  immobilize DNA migration during  electrophoresis at very low concentration and  form transfection complex within 5 minutes at  RT. A remarkable feature of the reagent is the  rapid and complete degradation of polymer  after transfection complex endocytosis (Figure  1), leading to much less cytotoxicity.  PolyJet™ reagent, 1.0 ml, is sufficient for  ~667 transfections in 24 well plates or ~333  transfections in 6 well plates, providing a  very affordable alternative to the leading  products for transfecting a variety of commonly used and hard-to-transfect mammalian  cells.

Examples Showing Transfection Efficiency of PolyJet™ DNA In Vitro Transfection Reagent on Commonly Used Cells



Transfection efficiency comparison of PolyJet™ vs. lipofectamine Plus on Chinese Hamster Ovary (CHO) cells. HA tagged beta-tubulin cDNA was delivered into CHO cells with PolyJet™ (left panel) and lipofectamine Plus (right panel) respectively. FITC conjugated antibody against HA tag was utilized to pick up HA-beta-tubulin (Green) while a DM1a antibody was used to detect endogenous alpha-tubulin followed by probing with rhodamine conjugated secondary antibody (Red). The above picture was provided by Dr. Shang Yin of University of Texas at Houston Medical School as courtesy


A comparison showing transfection efficiency of PolyJet™ reagent vs. a leading product, Lipofectamine 2000 on HEK293FT cells. HEK-293FT cells were transfected with GFP vector (pEGFP-N3) by PolyJet™ (left panel) and Lipofectamine 2000 (right panel) respectively. The cells were visualized by Nikon Eclipse Fluorescence microscope 24 hours post transfection



A comparison showing transfection efficiency of PolyJet™ reagent vs. a leading product, Lipofectamine 2000 on HepG2 cells. HepG2 cells were transfected with GFP vector (pEGFP-N3) by PolyJet™ (left panel) and Lipofectamine 2000 (right panel) respectively. The cells were visualized by Nikon Eclipse Fluorescence microscope 24 hours post transfection


Transfection efficiency comparison of PolyJet™ vs. Fugene HD on MDCK cells. A plain GFP DNA was transduced into MDCK cells with PolyJet™ (left panel) and Fugene HD (right panel) reagents respectively per manufacturers' protocols. GFP and DAPI staining were visualized under fluorescence microscopy 48 hours post tansfection. The above comparison data and pictures were completed and provided by Dr. Ge Zhou of NYU Medical Center as courtesy


A comparison showing transfection efficiency of PolyJet™ reagent vs. a leading product, Lipofectamine 2000 on MDCK cells. MDCK cells are notoriously hard to transfect. With proprietary "Shaved Cell Transfection" protocol, PolyJet™ (left panel) gives up to 70% GFP positive cells vs. Lipofectamine 2000 (right panel) around 5% efficiency. MDCK cells were transfected with GFP vector (pEGFP-N3) by PolyJet™ (left panel) and Lipofectamine 2000 (right panel) respectively. The cells were visualized by Nikon Eclipse Fluorescence microscope 36 hours post transfection


A comparison showing transfection efficiency of PolyJet™ reagent vs. a leading product, Fugene HD on LNCap cells. LNCap cells were transfected with GFP vector (pEGFP-N3) by PolyJet™ (left panel) and Fugene HD (right panel) respectively. The cells were visualized by Nikon Eclipse Fluorescence microscope 24 hours post transfection


Neuro2A cells transfected with pEGFP-C1 plasmid using PolyJet™ In Vitro DNA Transfection Reagent. The Neuro2A cells were visualized by Nikon Eclipse Fluorescence microscope with DIC phase imaging (left) and FITC imaging (right) 24 hours post-transfection


Comparison of cytotoxicity of PolyJet™ DNA In Vitro 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
