  • 70nm NHS-Activated Gold NanoUrchins Conjugation Kit (MIDI Scale-Up Kit, 10/ 3 reactions )

70nm NHS-Activated Gold NanoUrchins Conjugation Kit (MIDI Scale-Up Kit, 10/ 3 reactions )

70nm NHS-activated Gold NanoUrchin Conjugation Kit have been optimized for high efficiency one-step conjugation of proteins and other primary amine-containing ligands to Gold NanoUrchins.

The kit 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.

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

Kit Components

  • 70nm NHS-Activated Gold NanoUrchins (lyophilized) – 1 vial/ 3 Vials/ 10 vials
  • 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 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.
