Nano-W

NANO-W™ is a negative stain for electron microscopy (not available elsewhere) with excellent spreading and staining properties. It is an organo-tungstate compound and is stable, non-volatile in the beam and will not denature protein samples. It is especially useful for staining isolated molecules on a thin carbon film.

NANO-W™ is supplied ready-to-use, as a 2 % solution in water at pH 6.8.

NANO-W™ may be mixed with the lower atomic number NanoVan™ to produce intermediate stain densities.

NANO-W™ should be refrigerated upon receipt, and stored at 2 - 8°C.
