Product Information

Nano-W® Negative Stain for EM

Superior negative stains for electron microscopy

Nanoparticle precision for the tiniest targets

  • Uniform, electron-dense stain for EM
  • Dries without crystallization; perfect for EM grids
  • Visualize with ease:
    • edges of protein complexes
    • macromolecules
    • cells in suspension
  • Better than positive stains like osmium tetroxide:
    Won’t obscure labeling of biological structures

Visualize even your smallest targets!

Use with our Nanogold® labeling reagents

Available in tiny 0.8 and 1.4 nm, as well as 5 & 10 nm

Nano-W™

Based on an organotungsten compound

(Methylamine Tungstate)

High density, high contrast

Nano-W™ (methylamine tungstate) is a negative stain based on an organotungsten compound.

  • Excellent spreading qualities
  • High density for high contrast
  • May be mixed with the lower atomic number NanoVan™ to produce intermediate stain densities.
  • pH of 6.8.
