NHS-Activated Gold Nanoparticles

Cytodiagnostics NHS-activated Gold Nanoparticle Conjugation Kits have been optimized for high efficiency one-step conjugation of proteins and other primary amine-containing ligands to gold nanoparticles.

The kits contains ready-to-use pre-made mixtures. No activation or manipulation of the gold nanoparticles is required prior to conjugation, which often results in poor performing conjugates. Simply mix your protein with the pre-activated NHS ester gold nanoparticles supplied in the kit to generate your conjugate. 

The precisely engineered gold surface on our NHS ester-activated gold nanoparticles results in high conjugation efficiency and stable conjugates while minimizing non-specific binding in your assay. 

For quality control of antibody and antigen conjugation our Conjugation QC Lateral Flow Dipstick Kit can be used. 

Features & Benefits of NHS-Activated Gold Nanoparticles

• Results in covalently bound ligand and more stable conjugate.
• Fast and convenient one-step conjugation reaction with no pre-activation requirements.
• Spacer between the gold nanoparticle surface and conjugated ligand minimizes effects on the tertiary protein structure, which can lead to poor performing conjugates, a common problem seen in conjugates prepared by passive adsorption.
• Precisely engineering surface coating that reduces non-specific protein binding in biological assays.
