BioReady Gold Nanospheres – Carboxyl·

*One discount per customer

Antibodies and other amine-containing biomolecules efficiently bind to carboxyl gold nanoparticles using EDC-NHS chemistry.

PEG 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 water, and includes complimentary LabCon® centrifugation tubes.

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