Product Description
About
- Three small-range size of standard gold nanoparticles (12nm, 15nm, and 17nm) are combined in a convenient pack for testing optimal size, suitability, and stability during your protocol development.
Properties
- TORSKAL’s unconjugated gold nanoparticles are made using a unique proprietary protocol resulting in particles with superior size distribution and shape compared to that of the leading competitor.
- Our gold nanoparticle preparations have a narrow size distribution (SD of less than 10%), exceptional protein adsorption properties and more than 95% spherical particles.
- 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 4-8°C. Lower temperature prolongs the shelf life of the product.
- Do NOT freeze. Freezing causes irreversible aggregation of the gold nanoparticles.
- When stored as specified the product is stable for at least six months.
