Polyethyleneimine (PEI), particularly the linear form with a molecular weight (M.W.) of 25,000, is a synthetic polymer known for its high density of amine groups along the polymer backbone. This feature imparts the polymer with a strong cationic nature, making it highly effective in binding negatively charged particles, molecules, and cellular components. It is employed to enhance the characteristics of negatively charged dyes, augmenting their appearance and promoting their adhesion to surfaces. The polymer′s cationic nature allows it to form complexes with negatively charged nucleic acids, such as DNA and RNA, facilitating the encapsulation and protection of these molecules from enzymatic degradation. Furthermore, the PEI-nucleic acid complexes can interact with cell membranes, promoting cellular uptake through endocytosis.
