2-8°C

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.

Polyethylenimine (PEI) is a highly effective gene delivery vector, but because it is an off-the shelf material, its properties may not be optimal. To investigate the effects of the protonation properties of the polymer, we generated PEI derivatives by acetylating

Biomacromolecules, 7(8), 2427-2435 (2006-08-15)
We previously reported that gene delivery efficiency of 25-kDa, branched polyethylenimine (PEI) increased upon acetylation of up to 43% of the primary amines with acetic anhydride. In the present work, we investigated the effects of further increasing the degree of

Bioconjugate chemistry, 19(7), 1448-1455 (2008-06-17)
Polymer carriers like PEI which proved their efficiency in DNA delivery were found to be far less effective for the applications with siRNA. In the current study, we generated a number of nontoxic derivates of branched PEI through modification of
