NHS-Activated Gold NanoUrchins Conjugation

Cytodiagnostics NHS-activated Gold NanoUrchin 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 nanourchins is required prior to conjugation, which often results in poor performing conjugates. Simply mix your protein with the pre-activated NHS ester gold nanourchins supplied in the kit to generate your conjugate. 

The precisely engineered gold surface coat on our NHS ester-activated gold nanourchins 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 NanoUrchins

  • 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 nanourchin 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.
