Phosphotungstic acid-haematoxylin stain - Wikipedia
Phosphotungstic acid haematoxylin (PTAH) is a mix of haematoxylin with phosphotungstic acid, used in histology for staining. It stains some tissue in contrasting colors in a way similar to haematoxylin and eosin stain, as phosphotungstic acid binds to tissue proteins.
PURPOSE:Used for diagnosing muscle cross-striations and fibrin. PRINCIPLE:The amount of phosphotungstic acid in the staining solution is far greater than the amount of hematein and it is believed that tungsten binds all available components blue, while the phosphotungstic acid is thought to stain the red-brown components.
Phosphotungstic Acid-Haematoxylin Stain - ScienceDirect
Phosphotungstic acid-hematoxylin (PTAH) stain may be useful to confirm the presence of fibrin. Raja R. Seethala MD, in Surgical Pathology Clinics, 2014. Histochemical stains are often used to highlight stromal or cytoplasmic components.
Phosphotungstic Acid Hematoxylin (PTAH) Stain Kit (Connective ... - Abcam
The PTAH Stain Kit (Connective Tissue Stain) is intended for use in the histological visualization of collagen, striated muscle, glial fibers and collagen without using Zenker's Fixative containing mercuric chloride. This kit may be used on formalin-fixed, paraffin-embedded or frozen sections.
Phosphotungstic Acid-Hematoxylin Stain: Chemistry
The Phosphotungstic Acid-Hematoxylin (PTAH) staining method relies on acid-base chemistry to stain collagen and muscle fibers. These fibers are demonstrated using a tungsten mordant provided by the phosphotungstic acid.
Jan 17, 2019 · PRINCIPLE AND RESULTS: This stain is intended for use by laboratory professionals to stain routinely prepared paraffin embedded tissue specimens (in vitro) to identify collagen, fibrin and striated muscle without using Zenker's Fixative with Mercuric Chloride as a mordant. Fibrin and muscle stain blue, collagen brownish-red to red, and nuclei blue.
