Product Information 

NANOGOLD® is a newly developed gold immunoprobe.¹ NANOGOLD® reagents consist of affinity-purified Fab fragments and IgG antibodies (goat anti-mouse IgG, goat anti-mouse Fab, goat anti-rabbit IgG, goat anti-rabbit Fab, rabbit anti-goat IgG, rabbit anti-goat Fab, and a range of other polyclonal IgG antibodies and Fab fragments) or Streptavidin covalently conjugated to the 1.4 nm NANOGOLD® gold cluster label. NANOGOLD® can be used in immunoblotting, light microscopy, and electron microscopy to provide clear visibility. Stable to wide ranges of pH and ionic strength, this gold immunoprobe is 1.4 nm in diameter. It is not radioactive or carcinogenic. NANOGOLD® reagents are stored in 20 mM phosphate buffered saline (150 mM NaCl) at ph 7.4, with 0.1 % BSA and 0.05 % sodium azide as preservatives. NANOGOLD® conjugates should be stored at 2-8°C. DO NOT FREEZE。
