WebJul 16, 2015 · The electron beam can cross biological material easier than the surrounding space. The result resembles an inverted traditional TEM image (Figures 2, 4-7).The standard staining solution used today is an aqueous 1% phosphotungstic acid with pH 7.2. WebPhosphotungstic acid –hematoxylin (PTAH) highlights the abundant mitochondria, seen as deep blue cytoplasmic granularity and ranging from focal or patchy to diffuse. Striated duct epithelial cells, with their basally oriented interdigitating cytoplasmic processes and associated columns of mitochondria, may act as a positive internal control.
Phosphotungstic Acid - Preparation and Chemical Properties
WebPhosphotungstic acid hydrate is a heteropolyacid.It is a reagent suitable to detect alkaloids and nitrogenous bases. It is suitable for manufacturing organic pigments, and additives in the plating industry. It is known to impart water resistance to plastics, adhesives, and cement. It also is suitable as a catalyst for organic reactions.
