TransIntro^® PEI Transfection Reagent is a high-charged cationic polymer modified based on 40 KDa linear polyethylenimine (PEI). It can form PEI/DNA complexes with negatively charged DNA . The complexes can adhere to negatively charged cell surface residues, and then enters the eukaryotic cell through endocytosis. This product is manufactured and managed in accordance with GMP standards. Animal derived component free, low toxicity, high transfection efficiency, and simple operation. It is suitable for DNA transfection and multi-plasmid co-transfection of HEK-293 and other cell lines. It can be used in the large-scale recombinant protein expression and virus production.

Features 

• Wide application: It is suitable for transient transfection and stable transfection of various adherent or suspension cells such as HEK-293. 

• High transfection efficiency: It is suitable for high-efficiency transfection of plasmid DNA. Transfection efficiency of HEK-293 is more than 90%. 

• Low cytotoxicity: Adherent Cells has a good morphology after transfection. The cell activity rate of suspended cells is more than 90% after 24 hours of transfection. 

• Simple operation: No need to change the medium before and after transfection, tolerance with antibiotics and serum. 

• GMP Grade: Manufactured and managed in accordance with GMP standards.
