As a global leader in gold nanoparticle production, nanoComposix specializes in providing high-purity and monodisperse nanomaterials – delivering the quality you need for consistent results.
40 nm Protein G-conjugated spherical gold nanoparticles combine strong plasmonic optical properties with biofunctionalized surface chemistry. These nanoparticles offer high affinity binding to the Fc region of immunoglobulin G (IgG) from a variety of species. Protein G gold conjugates are used in high sensitivity lateral flow assays, immunoblotting, immunohistochemistry, imaging applications, and more.
nanoComposix provides high quality nanomaterials that are precisely engineered and highly characterized. All our products are supplied with a batch-specific Certificate of Analysis including characterization data such as TEM, DLS, Zeta, and UV-Vis.
Intended for Research Use Only. Contact us for custom formulations, ISO 13485/cGMP compliant materials, or bulk supply requirements.
