Uranyless is a non-radioactive staining reagent as alternative to uranyl acetate. An optimized lanthanide Mix allows fast staining times. Uranyless is suitable for classical and negative staining procedures. The 30ml dispenser bottle is sufficient for staining of up to 1500 TEM grids.
UranyLess in 30% Ethanol is recommended for dense and lipid-rich tissue which is difficult to stain. UranyLess in Acetone is used for contrasting cryo-fixed tissue during freeze substitution.
Small size (2ml), light-gauge, pre-scored amber glass ampoules. Ampoules containing OsO4 crystals are pre-cleaned and heat sealed in plastic bags to assure a contaminant-free solution.
