Synonyms: Acetylated PEI; Acetylated-PEI25K; Capped PEI
Linear Structural Formula: (C29H63N11O3)mC3H8N2O
Storage: 2-8C
Application: High molecular weight branched PEI is commonly used in gene delivery due to its high transfection efficiency in a broad range of cells. Branched PEI has been used to successfully deliver genetic material both in vitro and in vivo. N-Acetylation of PEI could lower its toxicity. At low degree of substitution (below 25%) resulted in moderate improvement of transfection activity.
