  1. Transporter™ 5 Transfection Reagent

    Transporter™ 5 Transfection Reagent

    Starting at: €49.00

    Transporter™ 5 Transfection Reagent is a ready-to-use transfection reagent based on a proprietary polyethylenimine derivative.  The structure of Transporter™ 5 condenses DNA into positively charged complexes which enter the cell by endocytosis.  Transporter™ 5 works exceptionally well for transfection of HEK-293, CHO, COS, HeLa, insect cell lines (Sf9 and Sf21) and a variety of other eukaryotic cell lines.

  2. Polyethylenimine, Linear, MW 25000, Transfection Grade (PEI 25K)

    Polyethylenimine, Linear, MW 25000, Transfection Grade (PEI 25K)

    Starting at: €210.00

    PEI 25K is a powerful, trusted, and cost-effective transient transfection reagent. In HEK293 and CHO expression systems, PEI offers consistently high gene expression on a wide scale (96 well plates up to 100 L bioreactors). Each year, more researchers and companies turn to Polysciences PEI to gain a critical edge in their work. Relative to most other options, using PEI to prepare transfection reagents in-house can offer as much as a 40% reduction in total transfection costs. Learn More
  3. Polyethylenimine HCl MAX, Linear, Mw 40,000 (PEI MAX 40K)

    Polyethylenimine HCl MAX, Linear, MW 40000, Transfection Grade (PEI MAX 40K)

    Starting at: €250.00

    PEI MAX 40K (also known as PEI 22K in free base) is a powerful, trusted, and cost-effective transient transfection reagent. In HEK293 and CHO expression systems, PEI offers consistently high gene expression on a wide scale (96 well plates up to 100 L bioreactors). Each year, more researchers and companies turn to Polysciences PEI to gain an edge in their critical work.
