Description	PEI Magnetic Beads are magnetic nanoparticles densely modified with branched polyethyleneimine (PEI), which endows the surface with a high density of positively charged amine groups across a wide pH range. Featuring strong electrostatic adsorption capacity and high biomolecule-loading efficiency, they are extensively used for gene delivery, nucleic acid extraction and purification, protein immobilization, enzyme conjugation, and polyanion capture, with high stability and reproducibility in biochemical workflows.
Applications	Biological molecule coupling, immobilization, construction of nano-probes, etc.
