About this item
PEIpro® is a ready to use 1 mg/ml optimised linear polyethylenimine (PEI) reagent for the production of virus and recombinant proteins by Transient Gene Expression (TGE) in suspension-adapted mammalian cell lines cultivated in shaker flasks, platform shakers or stirred tank bioreactors.
- Optimised PEI-based transfection reagent for scalable virus production
- Superior viral titres compared to other commercial PEIs and calcium phosphate
- Suitable for process development of large-scale virus production
- Free of animal-origin components
- Well characterised and lot release tested linear PEI
- Reliable and secure supply
PEIpro® undergoes full chemical testing and is compliant with the regulatory guidelines for raw materials used in bioproduction. The reagent is supplied with advanced quality controls including a specific transfection efficiency test that ensures excellent lot-to-lot consistency, and an implied license statement.
Since 1st of September 2021 Polyplus-Tranfection changed product part numbers. Products are remaining the same and the change is only related to the product part number. New product part numbers have symbol 'New'. For duplicated products with symbol 'telephone' please be informed that it’s the same product but with previous part number which we will only offer till the end of stock.
PEIpro® is fully synthetic and free of any component of animal-origin. The quality of PEIpro® is continuously assessed and documented during manufacturing with the appropriate control testings. Further systematic lot management and release testing is performed for each lot produced. A qualified transfection assay ensures reliability and reproducibility of the transfection efficiency under conditions suitable for biomanufacturing. PEIpro® undergoes sterility, mycoplasma and bacterial endotoxin testing according to pharmacopoeia standards.
