80nm Carboxylated (carboxyl-PEG3000-SH) Silver Nanoparticles functionalized gold nanourchins 15nm Maleimide-Activated Gold Nanoparticles (lyophilized)

15nm Maleimide-Activated Gold Nanoparticles (lyophilized) - 3 vials

Stable gold nanoparticle conjugates can readily be prepared by passive adsorption of a protein to the gold nanoparticle surface

4E+12 (when dissolved to a final volume of 1ml)

which is detected through the use of the supplied Protein A-Gold NanoUrchin Conjugate which gives a blue spot upon positive detection
