Phosphotungstic acid tem staining
WebMar 2, 2024 · Transmission electron microscopy (TEM) is used to detect the presence of fibrils using phosphotungstic acid as the staining dye . A solution of 2% phosphotungstic acid (PTA) was prepared in Distilled De-Ionized (DDI) water. A total of 3 μLof HEWL sample was placed on the grid. Immediately 3 μL of staining solution (PTA) was placed on the grid. WebMethods of preparation are given for phosphotungstic acid, 3H 2 O.P 2 O 5.24WO 3, as distinct from the sodium salt, 3Na 2 O.P 2 O 3, 24WO 3.NH 2 O. The acid has an approximate solubility in water at room temperature of 5 parts in 1 part of water and the sodium salt has a solubility of approximately 1 in 1 part of water.
