Abstract:The present work explores the ability of poly (1-vinyl imidazole) to complex si-RNA against vascular endothelial growth factor (VEGF) and its in vitro efficiency in A549 lung cancer cells. The polyplex formed was found to exhibit 66% complexation efficiency. The complexation was confirmed by gel retardation assay, FTIR and thermal analysis. The blank PVI polymer was not toxic to cells. The polyplex was found to exhibit excellent internalization and escaped the endosome effectively. The polyplex was more effect… Show more
