Gomori one-step trichrome stain is a histological staining technique used to differentiate and visualize various tissue components, including collagen fibers, muscle fibers, and cytoplasmic structures. It is a one-step method, meaning that all of the necessary staining agents are present in a single solution.
Under the microscope, collagen fibers appear bright red, muscle fibers appear green, and cytoplasmic structures appear blue. This allows for the visualization and differentiation of different tissue components.
The Gomori one-step trichrome stain is particularly useful in the diagnosis of various diseases, including muscular dystrophy, cirrhosis, and fibrosis. It can also be used to assess the quality of collagen in tissues such as skin, bone, and cartilage.
