Polyethyleneimine, 30% in water, is a cationic polymer that interacts with cellular and molecular components through electrostatic interactions. When introduced to a cellular environment, polyethyleneimine can bind to negatively charged molecules such as DNA, RNA, and proteins. This interaction can lead to the condensation of DNA and RNA, which may influence gene expression and protein synthesis within the cell. Polyethyleneimine disrupts cellular membranes, potentially affecting the permeability and integrity of the cell. This disruption can lead to changes in cellular signaling pathways and ion transport. Polyethyleneimine has the ability to form complexes with certain molecules, which can impact their stability and function within the cell. The cationic nature of polyethyleneimine allows it to interact with various cellular and molecular components, potentially influencing cellular processes and pathways.
