Staining Agents for EM

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.

 

Recommended for use with UranyLess (#DM22409).

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.
