Stains for electron microscopy
All stains are EM grade
| Ammonium molybdate | – | Irritant. Negative stain. |
| Indium trichloride | – | Corrosive. Metal stain for nucleic acids. |
| Lanthanum nitrate | – | Oxidising, irritant. Used to prepare colloidal lanthanum hydroxidecontaining fixatives for the demonstration of intercellular spaces. |
| Lead acetate. Toxic | – | Metal stain for TEM, used for in-block and thin section staining. |
| Lead citrate | – | Toxic. For the preparation of a simplified lead stain. The most widely used metal stain for ultrathin sections. Lead Citrate is a restricted chemical and can only be shipped within the EU. |
| Lead nitrate | – | Oxidising, toxic. Metal stain for ultrathin sections. |
| Methylamine Tungstate | – | 1g |
| Phosphomolybdic acid | – | Oxidising, corrosive. Positive and negative stain. |
| Phosphotungstic acid | – | Corrosive. Positive and negative stain. |
| Potassium pyroantimonate | – | Harmful |
| Ruthenium red | – | Positive stain. |
| Sodium silicotungstate | – | Negative stain. |
| Uranyl acetate | – | Very toxic, radioactive. Universal stain for thin sections, in-block staining and negative staining. |
Methylamine tungstate is an excellent negative stain.
Unlike phosphotungstic acid, it does not damage virus particles and is consequently valuable for staining delicate viruses.
Contrast is good, though not as good as that obtained with uranyl stains; the resolution is good, and the material wets grid films and specimens very well.
See Faberge A.C. and Olivier R.M., Microscopie 20, 242, 1974 for application to plant viruses.
