80nm Maleimide-Activated Gold NanoUrchins Conjugation Kit (3 Reactions)

Cytodiagnostics 80nm Maleimide-activated Gold NanoUrchin Conjugation Kit has been optimized for high efficiency one-step conjugation of thiol-containing ligands to gold 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 Maleimide gold nanourchins supplied in the kit. 

This mini kit contains 3 individual reaction vials with lyophilized maleimide-activated gold nanourchins for performing three independent conjugation reactions.

Kit Components

• 80nm Maleimide-Activated Gold NanoUrchins (lyophilized) - 3 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.
