Product Introduction:

Negative staining is a staining technique discovered by Hall in contrast to normal staining (i.e. positive staining). The principle lies in the use of heavy metal salts around the low electron density of the sample, to enhance the electron density around the sample, resulting in the "mass-thickness" difference between the fine structure, to enhance the scattering and absorption contrast, so that the sample in the dark background shows a bright structure. Negative staining solutions include phosphotungstic acid, ammonium molybdate, India ink, etc., of which the most commonly used is 1%-3% phosphotungstic acid. 
Phosphotungstic Acid Negative Staining Solution (2%) is suitable for displaying macromolecules, bacteria, viruses, protozoa, phages, organelles, nucleic acid macromolecules, protein crystals and other macromolecular materials. The image of the stained sample appears transparent and bright, while the background image is black.
