Streptavidin Gold NanoUrchin Conjugates

Streptavidin conjugated gold nanourchins can be used for secondary detection of biotinylated probes in assays such as immunoblotting, ELISA, light microscopy and electron microscopy applications.

Streptavidin gold nanourchin conjugates can also be used for convenient and fast conjugation of any biotinylated ligand such as antibodies and oligonucleotides to the gold surface.

Advantages of Gold Conjugates

  • Sensitive technique (100pg or less in dot blotting when used together with our silver enhancement kit)
  • This small gold nanoparticle conjugate is ideal for increasing sensitivity in immunohistochemistry protocols when used together with our silver enhancement kit for microscopy.
  • Provides a permanent label

Storage/Stability

  • Store undiluted in storage buffer at 2-8 degree Celsius. Stable for 4 months if stored as specified.
  • Storage of conjugate at working dilution may result in performance loss.
