GlossaryPolyethylenimine

polymer used for binding DNA and delivering genes

Polyethylenimine (PEI) is a polymer that is often used in scientific research and industrial applications due to its strong ability to bind to DNA and other negatively charged molecules. It is commonly utilized in gene therapy and biotechnology for delivering genetic material into cells, as well as in water treatment processes to remove contaminants.
