Rinse in deionized/distilled water. Place the slides in Phosphomolybdic/Phosphotungstic Acid Solution for 5-10 minutes. WebApr 13, 2024 · Grids were washed with water and stained with phosphotungstic acid for 1 min. After staining, grids were then washed with molecular-grade water. Then, the grids were examined at an acceleration voltage of 80 kV using a TEM (Tecnai G2 Spirit BIOTWIN, FEI, Eindhoven, The Netherlands).

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. The Preyssler-type phosphotungstate was a good negative staining reagent for T4 and other phages examined in the present study. The lambda phage (family Siphoviridae) has an icosahedral head with a diameter of ca. 60 nm, a long flexible tail with a length of ~ 150 nm, a short terminal fiber, and four tail … See more Figure 3 shows the TEM images of T4 phages obtained using two common negative staining reagents, uranyl acetate and neutralized Keggin-type PTA, and the … See more The concentration of K14[P5W30O110Na(H2O)] in the negative staining solution is an important factor affecting image clarity. We examined the concentration … See more Keggin-type and Preyssler-type phosphotungstates exhibit greatly different stabilities in neutral solution.
