BioPure Gold Nanospheres – PEG·

Polyethylene Glycol (PEG) is a 5 kDa ligand that is covalently bound to the particle’s surface. The PEG surface provides the highest stability in aqueous buffers and protic solvents. 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.
