Intended use: With over 99% purity, our endotoxin free silver nanoparticles are ideal for sensitive applications requiring a minimal amount of contaminants, such as cellular toxicity studies, immunological studies, and aseptic assays. This product is also well suited for conjugate development for blotting and electron microscopy applications.

Properties 

Silver nanoparticles are a great alternative to gold nanoparticles if absorption maximum is desired in between 400-500nm. Absorption in this lower range also allows for an increased dynamic range when developing multiplex experiments.

Cytodiagnostics silver nanoparticles are made using a unique proprietary protocol resulting in monodisperse particles and a narrow size distribution (CV <13%). This translates to improved performance in your experiment. In addition, core size batch-to-batch variation is small ensuring that you always end up with the same 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 in the dark at 4°C. 

Do NOT freeze. Freezing causes irreversible aggregation of the silver nanoparticles. 

When stored as specified the product is stable for at least 6 months.
