      Lead Citrate is a commonly used metal stain for ultra-thin sections for electron microscopy. The Lead Citrate – Ready to Use Solution is ideal as counterstain for samples stained with UranyLess to enhance the contrast. The 3% solution is provided in a 30ml airless dispenser bottle and syringe for TEM Stainer QG3100.

      Recommended for use with UranyLess (#DM22409).

        Uranyless is a new non-radioactive staining reagent as alternative to uranyl acetate. A newly composed 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.

        Recommended for use with Lead Citrate (#DM22410).

          Lead citrate is used as enhancer for heavy metal staining in electron microscopy. It binds to osmium and uranyl acetate and thereby enhances the contrast of several cellular structures. Due to its high reactivity with CO2 care has to be taken for the preparation of solutions and during usage.
