IVD Test Reagent/Kits, Electron Microscopy, Stain, Phosphotungstic Acid

Definition : Electron microscopy stains designed for staining cell specimens using phosphotungstic acid. These electron microscopy stains are mild acidic irritants which have the appearance of small, colorless-grayish or slightly yellow-green crystals. Phosphotungstic acid electron microscopy stains are odorless, soluble in water, electron dense, and opaque for electrons; some can produce either a positive or a negative stain. They are used commonly in histology for binding fibrin, collagen, and fibers of connective tissues, and also for replacing dye anions from these materials, selectively discoloring them.
