PEI is a commonly used polymer carrier in gene transfection. It consists of cationic polymers and can introduce nucleic acids into eukaryotic cells. In polymer-based transfection, exogenous DNA forms complexes with cationic polymers that enter host cells by endocytosis.
MCE PEI Transfection Reagent is designed based on 25 kDa PEI. It is modified by introducing functional genes to enhance the binding ability of DNA, and reduced the cytotoxicity. In addition, the cell uptake and the endosome escape functions of PEI modified was enhanced significantly.
MCE PEI Transfection Reagent is high-efficiency, low-toxicity, strong-stability, and suitable for many cell types, such as HEK-293、HEK-293T、CHO-K1、COS-1、COS-7、NIH/3T3、Sf9、HepG2 and HeLa et, even some hard-to-transfect cells. It can also be applied to large-scale recombinant protein expression and virus production.
