PEIpro® offers a seamless transition from process development to commercialization

The extensive research development invested in PEIpro® and the Polyplus® expertise on the manufacturing process has made it a unique PEI-based transfection reagent. As result, PEIpro® has become the gold reference among commercially available PEIs for cell and gene therapy. Three quality grades are available to guarantee the level of process qualification, quality controls, traceability and documentation adapted to each project stage. Both PEIpro® and PEIpro®-HQ are produced in an ISO:9001 environment guaranteeing a high-quality product, whereas the PEIpro®-GMP is produced in GMP certified facilities following ICH Q7 guidelines that ensure a validated aseptic manufacturing process.  

A scalable and reproducible transfection reagent ensuring a robust manufacturing process

To ensure  robust manufacturing , scale-up or scale-out therapeutic virus production with PEIpro® -HQ or PEIpro®-GMP are guaranteed to be comparable to production yields achieved at small scale with R&D grade PEIpro® during process development. PEIpro®  is manufactured and formulated using a highly controlled and strict manufacturing process. By ensuring reproducibility from one run to the next. PEIpro®  greatly facilitates process standardization: a key advantage for large-scale production. Moreover, PEIpro®  is released using advanced quality controls including a specification for transfection efficiency that guarantees excellent lot-to-lot consistency. 

Mitigate your risk management process using PEIpro®-GMP

The introduction of any starting or raw/ancillary material in the manufacturing process of ATMPs adds potential risk factors. By using PEIpro®-GMP as the transfection reagent to produce viral vectors, you can be confident that quality and safety are ensured. PEIpro®-GMP is manufactured in compliance with international GMP guidelines ICH Q7 and correspondingly with EU “Guidelines for good manufacturing practices for medicinal products for human and veterinary use” (ICH Q7 and EudraLex Vol 4, Part II and Annex I: Manufacture of Sterile Medicinal Products). PEIpro®-GMP is provided in bags with MPC connectors and weldable tubing suitable for use in closed systems to decrease contamination risks. A residual test, to analyze the transfection reagent present/absence in the drug product, is available through selected service providers.

they used it


"Genethon proudly uses PEIpro for production of pre-clinical batches of Lentivirus & AAV."
Franziska Bollmann
Process Technology Consultant , Sartorius
“With PEIpro® we were able to consistently obtain high titer lentivirus produced in suspension culture. Unlike with other transfection reagents, we didn't see any toxicity to the cells when using PEIpro®. The protocols and application support provided by Polyplus Transfection helped us to rapidly and efficiently find the optimal conditions for the transfection step.”
Michael Chambers
CEO at Aldevron
"Many of the plasmids made at Aldevron are used for lentivirus or AAV production. We have a lot of experience with different transfection agents. The scientists at Polyplus are world-class and have done a great job in developing enabling technologies like PEIpro-GMP."
National Research Council Canada
"At the NRC our preferred transfection agent is PEIpro (Polyplus-transfection); because this is GMP ready and in our hands gives highly reproducible titers."
