Polyplus-transfection has granted Merck rights to the prior use of PEI for transfection. Polyplus-transfection will also supply Merck sites worldwide with batches of high quality linear PEI transfection reagent. The reagent is specifically formulated and subject to appropriate quality controls (transfection activity and microbiological tests). These ensure reliable, safe and reproducible protein production in medium to large scale. In addition, by purchasing PEI from Polyplus-transfection, Merck benefits from an implied license regarding Polyplus’ intellectual property rights for the use of PEI in transient and stable transfection for research and commercial purposes.

Merck has access to all the commercial and custom transfection reagents within the Polyplus-transfection PEI reagent portfolio. This includes PEIpr(TM), the fastest growing product within this portfolio. Launched in 2012, PEIpro has been designed for larger scale Transient Gene Expression (TGE) users that require a cost effective, fully qualified and licensed linear PEI based transfection reagent.

“Biopharmaceutical products, especially monoclonal antibodies, continue to dominate the pharmaceutical industry. As “big pharma” companies continue to invest in this sector, transfection, and particularly larger scale ‘transient gene expression’ products have become a key technology in the research and early discovery phase,” said Mark Bloomfield, CEO of Polyplus-transfection. “This deal between Polyplus and Merck, a global player in the development of biopharmaceuticals, is the latest in a series of license and supply agreements for Polyplus’ global and national pharma, bio-pharma and protein expression services companies. This latest deal provides additional confirmation of the superiority of Polyplus PEI for bioproduction and the value of our intellectual property rights and knowhow in the field of PEI-mediated nucleic acid delivery.” 

Financial details were not disclosed.
