Negative Stains

NanoVan™ and Nano-W™ Pre-Made Negative Stains

Originally intended for staining samples with gold nanoparticles, these convenient ready-to-use pre-made negative stains have been since utilized for many other applications, including pre-screening samples for cryo-EM. NanoVan™is based on vanadium and thus gives lighter staining, for best visibility of gold and silver nanoparticles in the sample. Nano-W^® is tungsten-based and recommended for those cases when higher contrast is desired; it is comparable to PTA negative stain.

• Special organic compounds ensure better spreading and uniformity of the stain
• Dry without crystallization
• Perfect for visualizing macromolecules, edges of protein complexes, cells in suspension
• Allow the user to skip the time-consuming and hazardous task of weighing out the chemicals
