Storage and Handling

i-colloid gold and gold-alloy nanoparticles

  • Store at 4 °C. DO NOT FREEZE. Particles will irreversibly aggregate if frozen.
  • Storage in original container is recommended. Transferring to another container may affect stability and performance.
  • Particles may settle during long-term storage. Swirl (invert) bottle to ensure homogeneous suspension before use.
  • Use at room temperature.
  • Particles that are not fully functionalized are sensitive to irreversible salt-induced aggregation.
  • Perform conjugations in salt-free or low-salt buffers.
  • Centrifuge particles exactly according to protocols to prevent packing and aggregation.
  • Shelf-life guaranteed for 18 months after delivery when stored at 4 °C in unopened bottle.
