Staining Agents for EM

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.

Recommended for use with Lead Citrate (#DM22410).
