2% Phosphotungstic acid solution is suitable for displaying molecules, bacteria, viruses, protozoa, phages, cell organelles, nucleic acid molecules, protein crystal and other polymeric material. After staining, the sample image rendered transparent light, the background image is black. Negative staining is discovered by Hall with respect to general staining (ie positive staining), in terms of the principle that the use of heavy metal salts wrapped sample with low electron density, and enhance the electron density around the sample, caused minor structure between the "quality - thickness" differences, enhance scattering absorption contrast.
