A Novel Co-polymer Based on Hydroxypropyl α-Cyclodextrin Conjugated to Low Molecular Weight Polyethylenimine as an in Vitro Gene Delivery Vector

A novel co-polymer based on 2-hydroxypropyl-α-cyclodextrin cross-linked by low molecular weight polyethylenimine was synthesized as a gene delivery vector. The copolymer could bind and condense DNA tightly. It showed lower cytotoxicity than PEI 25kDa in SK-BR-3 cells. Transfection efficiency was inc...

Descripción
Sumario:A novel co-polymer based on 2-hydroxypropyl-α-cyclodextrin cross-linked by low molecular weight polyethylenimine was synthesized as a gene delivery vector. The copolymer could bind and condense DNA tightly. It showed lower cytotoxicity than PEI 25kDa in SK-BR-3 cells. Transfection efficiency was increased over 5.5-fold higher than PEI 25 kDa in SK-BR-3 cells in complete serum medium. It is a potential candidate vector for gene therapy.
