BioReady Gold Nanospheres – Bare (Carbonate)·

Carbonate is a smaller, less complex molecule with a lower affinity to the gold nanoparticle surface (relative to citrate). Its greater displaceability produces better performing conjugates with physisorption antibody attachment. Learn more ❯

BioReady products are specially formulated for the attachment of a molecular recognition element such as an antibody for lateral flow and biodiagnostics. Learn more ❯

Carbonate BioReady 40 nm gold is provided at 20 OD in water, and 80 nm is provided at 5 OD in aqueous potassium carbonate buffer.
