Linear PEI

Linear Polyethyleneimines (Linear PEI) are high-performance cationic polymers widely used in biotechnology and biopharmaceutical manufacturing due to their exceptional ability to bind and deliver DNA and RNA. Their linear structure promotes efficient complex formation, reduced cytotoxicity, and highly consistent transfection results across diverse mammalian cell lines. Ideal for gene expression studies, plasmid DNA delivery, viral vector production (AAV, LV, RV), and recombinant protein manufacturing, our Linear PEIs offer excellent nucleic acid complexation, batch-to-batch reliability, and scalability from small-scale research to industrial bioprocessing.
