Testimonials

 

Testimonial #1: Cell type: TH+ (neural cells derived differentiated from induced pluripotent stem cells)

Transfection reagent: EndoFectin™ Max

"I tested EndoFectin Max on TH+ neural cells, which are differentiated from induced pluripotent stem cells and are hard to transfect. EndoFectin Max transfected my cells at least as well or better than Lipofectamine 3000. EndoFectin Max is also easier to use. I transfect the cells overnight and, using other transfection methods, I risked cell loss due to lack of nutrients. This is not an issue with  EndoFectin Max, because it allows me to keep my cells in complete media during the entire incubation. I will get the entire lab on board to try EndoFectin Max".

          -Gabriela Novak, University of California at San Francisco

 

Testimonal #2. Cell type: 10T1/2

Transfection reagent: EndoFectin™ Max

"Endo Fectin max is a good transfection reagent as I compared other vendors for difficult to transfect cells. It’s less toxic to the cells. Expression of the transfected protein is comparable or slightly higher to other vendors and I recommend using Endo Fectin max"

           –Amrendra K Ajay, Harvard Medical School

 

Testimonal #3. Cell type: Vero

Transfection reagent: EndoFectin™ Max

"I did use your Endofectin Max reagent several times and was quite impressed. Not having to remove the transfection mix is a nice touch.  I compared it to Lipofectamine® 2000 as well as Fugene® 6 and I got about 2x transfection efficiency over each.  I'm working with Vero cells which are hard to transfect."

           – Jeff Davis, Arisan Therapeutics

 

Testimonal #4. Cell type: HEK293

Transfection reagent: EndoFectin™ Max

"HEK293 cells were transfected with either EndoFectin Max or Lipofectamine 3000 with a luciferase-expressing plasmid. The cells transfected with EndoFectin exhibited 2-3 fold greater luminescence values over the Lipofectamine-treated cells"

           –Angel Cid-Arregui, German Cancer Research Center, Heidelberg, Germany

 

Testimonal #5.

Transfection reagent: EndoFectin™ Lenti

"Endofectin Lenti has enabled us at the Viral Pseudotype Unit (VPU) to dramatically increase the titres of our influenza lentiviral pseudotypes. With titres exceeding 10^9 RLU/ml we can perform large scale screening projects with a single batch of virus."

           –George Carnell, Universities of Greenwich and Kent, Kent, United Kingdom

 

Testimonial #6: Cell type: HUVEC

Transfection reagent: EndoFectin™ Max

“We used EndoFectin Max on HUVEC cells. We can say that EndoFectin Max works well with this cell line relative to other transfection reagents.”

-Marcin Magierowski,Jagiellonian University Medical College, Krakow, Poland

 

Testimonial #7: Cell type: HEK293

Transfection reagent: EndoFectin™ Max

“I used EndoFectin Max for HEK293 cells. It has good efficiency and low toxicity.  I am regularly engineering cell lines and need a good reagent like this one.”

-Janice Thomas, Oncoveda Cancer Research Center, Medical Diagnostic Laboratories, LLC

 

Testimonial #8: Cell type: Mouse embryonic stem cells

Transfection reagent: EndoFectin™ Max

“We have been using EndoFectin Max for several months now for a variety of transfections (e.g. dsRNA, mRNA, plasmid DNA) in mouse ESCs (D3 cell line) and mESC-differentiated fibroblasts, and have been very pleased with our results…high efficiency and little to no toxicity. I'd definitely recommend this product to others.”

-William D'Angelo, The University of Southern Mississippi

 

Testimonial #9: Cell type: HEK293T

Transfection reagent: EndoFectin™ Max

“I got 65% transfection efficiency with EndoFectin Max on HEK293T cells. I would recommend this product to others.”

-Hemant Raj Joshi, Graduate Student, University of Utah

 

Testimonial #10: Cell type: Rat primary hippocampal neurons

Transfection reagent: EndoFectin™ Max

"My lab has had a chance to transfect primary hippocampal neurons with the sample you sent, and so far, it works really well!

From the attached image you'll see that the transfection might appear low…but for our imaging studies we need to see single neurons in their entirety. With too many transfectants, this becomes a problem. We typically see between 5-10% transfection rates of these cells with the sample. This is also about 10X the transfection rate compared to Lipofectamine 2000."

           – Michael Silverman, Assoc. Professor, Simon Fraser University
