General description

Azide functionalized gold nanoparticles are suitable for covalent conjugation of any molecule with a terminal alkyne through click chemistry. These gold nanoparticles allow for rapid generation of gold conjugates for subsequent use in downstream assays.

Azide functionalized gold nanoparticles are more than 95% spherical and have uniform size distribution (CV <12%).

Application

Ideal for development of gold conjugates for use in applications such as blotting, lateral flow assays, microscopy, and transmission electron microscopy (TEM).

Storage and Stability

When stored for a long period of time gold nanoparticles may sediment at the bottom of the vial, which is especially prominent for larger particle sizes. Prior to use, re-suspend the sedimented particles by thorough mixing until a homogenous solution is obtained.
