Composition: citric acid stabilized
Quantity: 20ml of each size
Buffer: Supplied in 0.1mM Phosphate Buffered Saline (PBS)
Four sizes of standard unconjugated Gold NanoUrchin preparations combined in a convenient kit for testing optimal size, suitability and stability during your protocol conjugate development.
Properties
Our Gold NanoUrchins are unique spherical gold nanoparticles with spiky protrusions, which leads to 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. 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 to guarantee size and monodispersity. Lot specifications are included with every shipment.
Storage
Store product away from direct sunlight at 4-25°C. Lower temperature prolongs the shelf life of the product.
Do NOT freeze.
When stored as specified the product is stable for at least six months.
