BioReady Covalent Conjugate Optimization Kit
Gold Nanoshells are ultra-bright labels for lateral flow – providing up to 20× increases in sensitivity compared to 40 nm gold.
The BioReady Covalent Conjugate Optimization Kit provides everything you need* to get started optimizing your conjugation to Gold Nanoshells:
- Detailed protocol walks through the recommended first 4 experimental sweeps when optimizing a new conjugation
- Kit includes verified reagents & protocols including gold nanoshells, antibody purification filter, single-use EDC & NHS for 3 conjugation sweeps, reaction buffers, block buffer, and more
Gold nanoshell particles have a 120 nm silica core with a 15 nm gold shell; functionalized with a carboxyl (–COOH) surface and ready for covalent conjugation. Provided at 20 OD in 0.02 potassium carbonate solution.

Which Surface Should I Choose?
|Carboxyl||Learn more +||Covalent||
BioReady carboxyl (–COOH) gold is an effective and economical nanoparticle for covalent conjugations to proteins through carbodiimide crosslinker chemistry. Covalent coupling of proteins (e.g. antibodies) to a gold nanoparticle surface yields robust and stable gold particle conjugates. The nanoparticles are surface functionalized with a tightly bound monolayer that contains terminal carboxylic acid functional groups which can be activated through EDC/Sulfo-NHS chemistry to generate gold nanoparticle-antibody amide bonds. The EDC/Sulfo-NHS chemistry requires an extra step to activate the carboxyl group but can be performed at scale at reasonable cost, making carboxyl gold the most cost-effective method of covalently binding antibodies to gold.
