Polyethylenimine (PEI) Transfection Reagent

Polyethylenimine (PEI) with an average molecular weight of 40kDa is one of the most widely used cationic polymer based transfection reagents. its high water solubility enables effcient binding to negatively charged nucleic acids forming stable PEI-DNA complexes that facilitate endocytosis through interactions with the cell membrane.
 
Product features
• Low toxicity: combined with high transfection efficiency across diverse
cell types, including HEK293, CHO, and HeLa cell lines.
• Mature synthesis process: that ensures reproducibility and cost effectiveness.
• Structural flexibility: through chemical modification, allowing optimization
for specific research or industerial needs.
Together, these properties make PEI a powerful and versatile tool for both
fundamental research and large scale biopharmaceutical production.
 
Storage
