Description
By utilizing our innovative and proprietary lipid conjugation technology, LipoD293™ (Ver. II) is specially designed and formulated by adding proprietary enhancers for transfecting HEK293 cells and other mammalian cells (Figure 1). As a 2nd generation liposome based DNA transfection reagent, LipoD293™ (Ver. II) offers extremely high transfection efficiencies for HEK293 related cells as well as many mammalian cells with less cytotoxicity. LipoD293™ reagent (Ver. II), upgraded from its previous version with refined chemistry, is 3~4 times more efficient in gene delivery. LipoD293™ reagent (Ver. II), 1.0 ml, is sufficient for ~666 transfections in 24 well plates or ~333 transfections in 6 well plates.

Comparisons of Transfection Efficiency of LipoD293™ DNA In Vitro Transfection Reagent (Ver. II) with Brand Name Products


Comparison of transfection efficiency of LipoD293™ reagent (Ver. II) vs. lipofectamine 2000 (L2K) and Fugene HD on HepG2 cells.
Right Panel: Comparison of transfection efficiency of LipoD293 (Ver. II) with Lipofecatmine 2000 (L2K), and Fugene HD on HepG2 cells. GFP DNA (pEGFP-N3) was transfected with different transfection reagents per manufacturer's protocols to HepG2 cell (cultured on Collagen pretreated dishes). GFP positive cell (%) and fluorescence intensity were detected by passing through FACS 48 hours post transfection
Left Panel: presence of serum and antibiotics enhances LipoD293 (Ver. II) efficiency on HepG2 cells. HepG2 cell (grown on collagen treated dishes) was transfected with three different conditions-------serum and antibiotics free, presence of 10% serum and antibiotics followed by removal 5 hours post transfection and presence of 10% serum and antibiotics without removal 5 hours post transfection.


Comparison of transfection efficiency of LipoD293™ reagent (Ver. II) vs. lipofectamine 2000 (L2K), TransIT and Fugene 6 on CHO cells.
Right Panel: Comparison of transfection efficiency of LipoD293 (Ver. II) with Lipofecatmine 2000 (L2K), TransIT and Fugene 6 on CHO cells. DNAs encoding Renilla luciferase (phRL-CMV) and GFP (pEGFP-N3) were transfected with different DNA transfection reagent per manufacturer's protocols. Renilla luciferase activity and GFP fluorescence were detected with Renilla Assay System and a Nikon Eclipse fluorescent microcopy respectively 24 hours post transfection.
Left Panel: Comparison of price ($/1.0 ml vial) of LipoD293 versus those of Lipofecatmine 2000 (L2K), TransIT and Fugene 6. All the prices were collected from the manufacturers' websites.


A comparison of transfection efficiency of LipoD293™ reagent with lipofectamine 2000 (L2K) on a hard-to-transfect cell, primary rat aortic smooth muscle cells. The rat aortic smooth muscle cells were prepared and transfected with pEGFP-N3 by LipoD293™ reagent (left panel) and Lipofecatmine 2000 (L2K, right panel) respectively per manufacturers' protocols. The transfection efficiency was evaluated by detecting GFP fluorescence with a Nikon Eclipse 2000 microscopy 24 hours post transfection. The above pictures were kindly provided by Dr. Nickolai Dulin of Section of Pulmonary and Critical Care, University of Chicago.


A comparison of transfection efficiency of LipoD293™ reagent with Fugene HD on hard-to-transfect cell, LNCap cells. The LNCap cells were grown as ATCC recommended procedures and co-transfected with pBabe-hygro-SSeCKs (1.5ug) and pEGFP-N3 (0.5ug) per well (6 well plate) LipoD293™ reagent (left panel) and Fugene HD (right panel) respectively per manufacturers' protocols. The transfection efficiency was evaluated by detecting GFP fluorescence with a Nikon Eclipse 2000 microscopy 24 hours post transfection. The above pictures were kindly provided by Dr. Lyn Gao of Roswell Park Cancer Institute.


Two examples showing exceptional efficiency of LipoD293™ reagent on hard-to-transfect cells like HepG2 and SaoS-2 cells. HepG2 and SaoS-2 cells in 95% confluency were transfected with pEGFP-N3 and pSV-β-galactosidase DNAs respectively in presence of serum/antibiotics. The efficiency was checked 48 hours post transfection by Zeiss 510 Confocal Microscopy and β-galactosidase staining kit respectively.



A comparison of transfection efficiency of LipoD293™ reagent with 293fectin on HEK293 cells. HEK293 cells transfected with pEGFP-C1 plasmid using LipoD293™ In Vitro DNA Transfection Reagent (Ver. II) (upper panel) and the most popular brand product 293fectin™ of Invitrogen (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.



A comparison of LipoD293™ (Ver. II) and Lipofecatmine LTX (LTX) on generation of Lentivirus (LV). Three cDNAs were co-transfected with LipoD293™ (Ver. II) and Lipofectamine LTX (LTX) into 293FT cells. A GFP vector, pHR-SIN-cppt-CMVEWP, was used to determine titer of LV. 1x105 293F cells per well was plated in to a 24 well plate followed by addition of different of amounts of the vector supernatant, 1 microliter (upper panel) and 10 microliters (lower panel) respectively. 5 days later, the cells was passed with FACS. The numbers at the upper right corner indicate the percentage of transduced cells. The titers of LV generated with LipoD293™ and L2K were quantified to be 8x10^6 and 3x10^6 tu/ml respectively

Testimonials
I am absolutely thrilled with the LipoD293 transfection reagent! I compared LipoD293 to Lipofectamine for transfection of plasmids to generate viral pseudoparticles and WOW! I recovered 4 times more virus using the LipoD293 reagent than Lipofectamine!! This is wonderful news for me and my mentor as it means that I don't have to spend so much time (and resources) on transfecting 293T cells to recover virus for in vitro experiments. My mentor was also very happy that LipoD293 costs much less than Lipofectamine!! We have already ordered 5 mls of LipoD293 and I have now convinced my lab mates to switch to LipoD293 since I got such good results with it. Thanks for making such a great product!

I wanted to update you on the free sample of LipoD293 that you sent to us. I recently transfected some Plat-E's side-by-side with Lipofectamine 2000, and your product out-performed it!!! We are also validating it with HeLa cells, but otherwise we are VERY happy with what we have seen thus far! Thank you for sending us the free sample, it definately made the SALE for us!
--------Catherine Gallo, Ph.D., University of Cincinnati

we have now tried the LipoD293 DNA In Vitro transfection reagent on 293FT cells. In the first flask we used the protocol by Invitrogen provided in theVirapower box insert (Virapower, pBABE-GFP plasmid, plus Lipofectamine). In the second flask we used LipoD293 (30 ul/6ml media) with the same amounts of Virapower and plasmid as in the first flask. The results were stunning:LipoD293 gave twice as many transformants as Lipofectamine 2000...
