60nm Maleimide-Activated Gold Nanoparticle Conjugation Kit (MIDI Scale-Up Kit)

SKU: MG10K-60-3

$465.00

CytoGroup 60nm Maleimide-Activated Gold Nanoparticle Conjugation Kit have been optimized for high efficiency one-step conjugation of thiol-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 maleimide gold nanoparticles supplied in the kit. 

This MIDI kit contains 1 vial with lyophilized maleimide-activated gold nanoparticles for performing one independent scale-up conjugation reaction.

Kit Components

  • 60nm Maleimide-Activated Gold Nanoparticles (lyophilized) - 1 vial
  • Protein Resuspension Buffer
  • Reaction Buffer
  • Quencher Solution

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.
