Polyethylenimine 'Max' (PEI MAX®) is a powerful, trusted, and cost-effective reagent widely considered as a current gold standard for both in vitro and in vivo transfection. PEI MAX® has a high density of protonatable amino groups, with amino nitrogen as every third atom. This imparts a high buffering ability at nearly any pH. Hence, once inside the endosome, PEI MAX® disrupts the vacuole and releases the genetic material into the cytoplasm. Stable complexation with DNA, efficient entry into the cell, and ability to escape the endosome makes PEI MAX® a highly efficient transfection reagent which is compatible for a wide range of cell lines/types including the most commonly used HEK293 and CHO cells grown in adherent and suspension cultures. PEI MAX® is capable of yielding high efficiency cell lines without compromising cell viability compared to other PEI and liposomal transfection reagents available in the market.
