What is another name for the PTAH stain used for fibrin, collagen, and myelin?

The PTAH stain, which stands for Phosphotungstic Acid Hematoxylin, is often associated with the detection of fibrin, collagen, and myelin within tissue samples. Mallory's stain, a name that references the staining technique developed by Dr. H. Mallory, incorporates the PTAH method and is specifically adept at highlighting connective tissue elements and fibrin in histopathological specimens. This staining method provides excellent contrast, allowing for the visualization of collagen fibers and fibrin deposits, which are critical in diagnosing various histopathological conditions.

In contrast, other staining methods mentioned serve different purposes or highlight different components within tissues. Lissamine's fast red is more associated with staining certain proteins and cellular components rather than specifically targeting fibrin, collagen, or myelin. Gomori Calcium is used for identifying calcium deposits, often in the context of assessing pathological conditions related to calcium metabolism, thus not relevant to the PTAH stain's focus as described. Masson's trichrome stain, while also useful for staining collagen and muscle fibers, is distinct in its methodology and application, especially with its component of differentiating muscle, fibrin, and collagen. Thus, Mallory's stain, reflecting the use of PTAH,
