Reactant Free Gold Nanoparticles

Home Reactant Free Gold Nanoparticles

Cytodiagnostics Reactant Free Gold Nanoparticles are supplied in 0.1mM phosphate buffered saline (PBS) and is extensively purified to be 99% free of residual reactants from manufacturing.

These particles have the same high protein binding efficiency as our standard gold nanoparticle preparations for use in applications such as conjugate development, lateral flow and Surface Enhanced Raman Spectroscopy (SERS) with the added benefit of being reactant free for more sensitive applications such as cell work and nanotoxicology studies.
