BioReady Gold Nanoshells – Carboxyl·

*One discount per customer

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 0.02 mM potassium carbonate solution, and includes complimentary LabCon® centrifugation tubes.

Please use included centrifugation tubes. Learn more about why these tubes are necessary ❯
