Movat's stain
Movat's stain (pronounced: mo-vat's stain) is a histological stain used in pathology to visualize and differentiate various tissue components. It was named after the Canadian pathologist Henry Zoltan Movat who developed it in 1955.
Etymology
The term "Movat's stain" is derived from the name of its developer, Dr. Henry Zoltan Movat, a Canadian pathologist. The term "stain" in this context refers to the process of adding color to microscopic specimens to enhance visibility and differentiation of their structures.
Usage
Movat's stain is a pentachrome stain, meaning it uses five colors to differentiate various tissue components. It is particularly useful in the study of connective tissue, as it can distinguish between collagen, elastin, smooth muscle, mucin, and fibrin.
Procedure
The procedure for Movat's stain involves several steps, each using a different dye to stain a specific component of the tissue. The dyes used include Alcian blue, Verhoeff's stain, Crocein scarlet, Brilliant green, and Safranin.
