BioReady Gold Nanoshells – Carboxyl

Antibodies and other amine-containing biomolecules efficiently bind to carboxyl gold nanoshells using EDC-NHS chemistry to make highly stable conjugates. Gold nanoshells provide an ultrabright label for lateral flow – up to 20× increases in lateral flow diagnostic sensitivity over 40 nm gold.

Carboxyl is covalently bound to the metal surface. The acid provides a highly negatively charged surface for subsequent conjugation to proteins, antibodies or peptides. 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 ❯

Provided at 20 OD in a .02 mM potassium carbonate solution.
