Elastic Fiber (Elastic Fiber) is mainly distributed in the arterial wall, alveolar wall and skin of human body, which is yellow when fresh and has strong refractive property. Commonly used elastic fiber staining methods include Gomori aldehyde magenta method, resorcinol alkaline magenta method, lichen red method, Victoria blue method, iron iodine hematoxylin method and so on. Resorcinol basic magenta staining solution is mainly used for elastic fiber staining, also known as Weigert resin phenol complex red staining solution. Elastic fiber staining can show the changes of elastic fibers in skin tissues, such as elastic fiber nevus, skin ring granuloma, hardness disease, etc.; show and determine the endocardium and arterial lesions, observe certain lesions are accompanied by elastic fiber proliferation or destruction; also can identify tumor tissue components such as elastic fibrous tumors, elastic fiber staining, can be clearly seen within the tumor elastic fiber ball.

Elastic fiber staining solution (modified Gomori aldehyde magenta method) staining principle lies in the mature aldehyde magenta on special proteins and mucopolysaccharides containing sulfate has a strong affinity for elastic fibers, and the elastic fibers combined with a very good, the staining solution also shows mast cell particles, lipofuscin, eosinophils and so on.
