Intended use:
Conjugate development by passive adsorption of proteins and other ligands to the gold nanoparticle surface. The resulting conjugate can be used in blotting, electron microscopy and immunohistochemistry applications.  

Properties

Our Gold NanoUrchins are unique spherical gold nanoparticles with spiky protrusion, which results in absorption of light in the far-red. 

Our Gold NanoUrchins have a narrow size distribution (CV of less than 8%) and exceptional protein adsorption properties. In addition, low batch to batch variability (+/- 2nm) assures you as a customer always end up with a product within the specified size range ordered.

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 4-25°C. Lower temperature prolongs the shelf life of the product.

Do NOT freeze. Freezing causes irreversible aggregation of the Gold NanoUrchins.

When stored as specified the product is stable for at least six months.
