Plasmid Transfection Reagent: sc-108061

Plasmid Transfection Reagent is a biochemical tool used to introduce plasmids into eukaryotic cells, a core technique in molecular biology, biotechnology, and genetic research. This reagent typically comprises cationic lipids or polymers that facilitate the delivery of negatively charged DNA molecules into cells through a process known as transfection. The key mechanism of action for Plasmid Transfection Reagent involves the formation of complexes with plasmid DNA via electrostatic interactions. These complexes, often referred to as lipoplexes or polyplexes when using lipid-based or polymer-based reagents respectively, help neutralize the charge of the DNA, thereby enhancing its ability to cross the predominantly negatively charged cellular membranes. Once inside the cell, these complexes escape the endosomes, a process aided by the fusogenic properties of the lipids or by the buffering capacity of the polymers, which leads to an increase in endosomal pH, causing the endosome to rupture and release the DNA into the cytoplasm.
