20 nm BioReady Gold Nanospheres for Covalent Conjugation
Customers outside of the US & Canada: please visit your local distributor’s website to purchase this item using its SKU, or contact us here. Thank you!
20 nm spherical gold nanoparticles for covalent conjugation are useful in applications such as biosensors, immunodiagnostics, and lateral flow assays.
BioReady™ Gold Nanospheres have carboxyl covalently bound to the metal surface. Antibodies and other amine-containing biomolecules efficiently bind to carboxyl gold nanospheres using EDC-NHS chemistry to make highly stable conjugates. Review our conjugation protocol or contact our experts for support.
nanoComposix provides high quality, monodisperse, and aggregation-free nanomaterials. All our products are supplied with a batch-specific Certificate of Analysis including characterization data such as TEM, DLS, Zeta, and UV-Vis.
