PEI STAR™ transfection reagent
Chemical Name: Poly[imino(1,2-ethanediyl)] hydrochloride
Biological ActivityPEI STAR™ is a chemically-defined, high-performance polyethylenimine (PEI) transfection reagent for cost-effective, affordable and scalable transient gene expression. PEI is a synthetic polymer with an exceptionally high positive charge density in pH-neutral solutions. Positively charged PEI binds strongly to negatively charged DNA and imparts a net cationic charge, allowing the DNA to enter cells. PEI is a non-viral vector commonly used to transfect HEK293 and CHO cells. Applications include production of recombinant proteins, antibodies and viruses.

Application of PEI STAR™ transfection reagent. PEI STAR™ performance data comparison (HEK293): HEK 293 - 20 mL cultures containing HEK293 suspensions were transfected with a CMV-SEAP plasmid at optimized PEI/DNA ratios using either PEI STAR™ (3:1) or leading competitor PEI. SEAP expression levels were quantified 5 days post-transfection using phosphatase reporter dye and UV/Vis absorbance.
Application of PEI STAR™ transfection reagent. PEI STAR™ performance data comparison (CHO): CHO - 20 mL cultures containing CHO suspensions were transfected with a CMV-SEAP plasmid at optimized PEI/DNA ratios using either PEI STAR™ (5:1) or leading competitor PEI. SEAP expression levels were quantified 5 days post-transfection using phosphatase reporter dye and UV/Vis absorbance.
