BioPure Silver Nanospheres – BPEI·

Branched Polyethylenimine (BPEI) is a 25 kDa polymer which contains a large number of free amines on the particle surface that are available for charge interactions with other target biomolecules or substrates. Learn more ❯

BioPure materials are high quality, unagglomerated, and monodisperse nanoparticles. Extensively purified and provided sterile with low endotoxin. Ideal for in-vivo and in-vitro studies and medical applications. Learn more ❯

Provided at 1 mg/mL in water.
