Contrasting Agents for EM (12 products in this category)

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. A ready-to-use solution in a 30ml airless dispenser bottle.

Recommended for use with UranyLess (#E22409).

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 (#E22410).

Platinum Blue is a newly developed non-radioactive substitutional EM stain when uranyl acetate is unavailable do to safety regulations. For various tissues Platinum Blue shows improved results compared to EMS UAR Replacement (E22405).

Uranyl acetate, from depleted uranium, a universal EM contrasting agent for thin sections, en-block stainings, and negative stainings.
