Overview of 250 nm Endotoxin Free Gold Nanoparticles

Inquiry

Description

Our 250 nm endotoxin free gold nanoparticles are specifically designed to have endotoxin levels of no more than 0.5 EU/mL as verified by the Limulus amebocyte lysate (LAL) test. This ensures that they can be safely used in biological systems without causing unwanted immune responses or other adverse effects.

Properties

Our 250 nm endotoxin free gold nanoparticle preparations have a tight size distribution (CV <8%), excellent protein adsorption abilities and more than 95% spherical particles. And with low batch-to-batch variability (+/- 2nm), you can trust that you'll always receive a product within the specified size range. In addition, each of our batches undergoes rigorous quality control using dynamic light scattering to ensure size and monodispersity, and lot specifications are provided with every product shipment.

Intended Use

Our highly purified 250 nm endotoxin free gold nanoparticles are ideal for sensitive applications requiring minimal contaminants, such as cytotoxicity studies, immunology studies, and sterility assays.

Storage

• Store the product at 4-25 °C away from direct sunlight. Cooler temperatures extend the shelf life of the product.
• Do not freeze. Freezing causes irreversible aggregation of the gold nanoparticles.
• The product is stable for at least six months when stored as specified.
