Use
Polyethyleneimines (PEIs) are highly basic and positively charged aliphatic polymers, containing primary, secondary and tertiary amino groups in a 1:2:1 ratio. For a long time, PEI has been also used in non-pharmaceutical processes, including water purification, paper and shampoo manufacturing. It has been also reported that PEI is relatively safe for internal use in animals and humans. PEI is widely used to flocculate cellular contaminants, nucleic acids, lipids and debris from cellular homogenates to facilitate purification of soluble proteins. Enzymatic reactions in bioprocesses constitute another field in which PEI was used: as an immobilizing agent for biocatalysts, as a soluble carrier of enzymes or in the formation of macrocyclic metal complexes mimicking metalloenzymes. PEI is also a common ingredient in a variety of formulations ranging from washing agents to packaging materials.
