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 are Gomori aldehyde magenta method, resorcinol alkaline magenta method, lichen red method, Victoria blue method, iron iodine hematoxylin method, etc. Elastic fiber staining can show the changes of elastic fibers in the skin tissues, such as elastic fibers nevus, cutaneous annular granuloma, hardness disease, etc.; to show and determine the endocardial and arterial lesions, to observe whether some lesions are accompanied with elastic fibers proliferation or destruction; can also identify tumor tissue components such as elastic fibers, and can also be used to identify tumor tissue components such as elastic fibers, and can also be used for the identification of the elastic fibers in the skin. It can also identify tumor tissue components such as elastofibroma, and the elastic fiber ball can be clearly seen in the tumor after elastic fiber staining.

Lichen red elastic fiber staining solution is easy to operate and has high specificity, but the staining effect may be varied by different batches of raw materials, and sometimes it will stain lipofuscin in hepatocytes.
