What is progressive staining?

Progressive staining occurs when the hematoxylin is added to the tissue without being followed by a differentiator to remove excess dye. Modified progressive staining occurs when a mild differentiator is used not to remove excess stain from the nuclei, but rather removes background staining.

What are the special stains in histopathology?

What is reticulin in liver?

Reticulin is used to assess liver architecture. It highlights the reticulin fibers (type III collagen) in the space of Disse, which helps to show the thickness of hepatocyte plates. Further, reticulin makes it easier to visualize areas of hepatocyte loss (collapse) or regeneration (increased thickness).

What stains myelin?

Procedure. Luxol fast blue is a copper phthalocyanine dye that is soluble in alcohol and is attracted to bases found in the lipoproteins of the myelin sheath. Under the stain, myelin fibers appear blue, neuropil appears pink, and nerve cells appear purple.
