Properties

Cytodiagnostics Ni-NTA functionalized gold nanoparticles are suitable for binding of proteins with a C-, or N-terminal 6X His tag. 

These gold nanoparticles allow for rapid generation of gold conjugates of any histidine-tagged protein that can subsequently be used as a probe in downstream applications. 

Our Ni-NTA functionalized gold nanoparticles are available in 12 different sizes ranging from 5 -100nm, are more than 95% spherical and have uniform size distribution (CV <12%). 

All of our batches go through stringent quality control prior to shipment to our customers using dynamic light scattering to guarantee size and monodispersity and lot specifications are supplied with each product.

Storage

Store product away from direct sunlight at 4°C. Do NOT freeze. When stored as specified the product is stable for at least twelve months.
