Linear Polyethylenimine

The Linear Polyethylenimine collection features high-charge, cationic polymer grades of PEI in various molecular weights (e.g., MW 2,500; 4,000; 25,000; 40,000) designed for binding anionic substrates, gene transfection applications, and surface functionalization. These linear PEIs (all secondary amines) differ from branched PEIs in structure and performance.

Product vial of Polyethylenimine, Linear, MW 25,000, Transfection Grade (PEI 25K™), used for high-efficiency gene transfection in molecular biology and biotechnology applications.
