40nm NHS-Activated Gold Nanoparticle Conjugation Kit (MIDI Scale-Up Kit)
RN-CY-CGN5K-40-3
Cytodiagnostics 40nm NHS-activated Gold Nanoparticle Conjugation Kit have been optimized for high efficiency one-step covalent conjugation of proteins and other primary amine-containing ligands to gold nanoparticles.
The kit 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.
This MIDI kit contains 1 vial with lyophilized NHS-activated gold nanoparticles for performing one independent scale-up conjugation reaction.

Activated Gold Nanoparticle
Kit Components
- 40nm NHS-Activated Gold Nanoparticles (lyophilized) – 10 vials
- Protein Resuspension Buffer – 1.5ml
- Reaction Buffer – 1.5ml
- Quencher Solution – 1.5ml
Features & Benefits
- 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.
