Nanoparticles, Endotoxin Free, Gold NanoUrchins
Intended use: Our extensively purified endotoxin free Gold NanoUrchins are ideal for sensitive applications requiring a minimal amount of contaminants, such as cellular toxicity studies, immunological studies, and aseptic assays. This product is well suited for conjugate development by passive adsorption of proteins and other ligands to the gold nanoparticle surface. The resulting conjugate can then be used in downstream applications.
Properties
Cytodiagnostics Gold NanoUrchins are unique spherical gold nanoparticles with spiky protrusions, which result in absorption of light in the far-red. They are made using a unique proprietary protocol resulting in pure, reactant free particles with excellent size distribution.
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. The endotoxin levels of all batches are validated by the Limulus amebocyte lysate (LAL) test and do not exceed 0.5 EU/mL.
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.
