Polyplus-transfection Licenses Kempbio for Mammalian Transient Transfection Technology
News May 19, 2010
Polyplus-transfection SA has announced that Kempbio, Inc., a provider of high quality bioservices to the biotechnology and biopharmaceutical industry, has signed a license agreement to use polyethylenimine (PEI) for the transfection of cells used for the production of recombinant proteins.
By signing this license, Kempbio becomes one of Polyplus’ sub-licensees for the use of PEI technology for the expression of proteins on milligram and gram scales using the human cell line HEK-293 and other mammalian host cells.
The production of recombinant proteins in human cell lines results in authentic human post-translational processing providing advantages for the stability and biological activity of proteins useful in the development of human therapeutics and diagnostic reagents.
“We are truly delighted to sign this license agreement with Kempbio, a company offering quality cell culture and protein expression services,” said Mark Bloomfield, CEO of Polyplus-transfection. “PEI is clearly the reagent of choice for research into large-scale mammalian transient transfection, and this agreement allows Kempbio to use PEI for its transfection services offering. Our business relationship with Kembio also demonstrates the significant value of our intellectual property rights in the field of PEI-mediated nucleic acid delivery.”
Financial terms were not disclosed.
Bubble formation is typically a much more random process than liquid droplet formation, yet the generation of uniform drops and bubbles is very desirable in microfluidics. Researchers have now shown that under certain conditions, bubbles can also be coaxed to form spheres as perfectly matched as droplets.READ MORE
