Elastic fiber (Elastic Fiber) is mainly distributed in the human arterial wall, alveolar wall, skin, freshly yellow, refractive, commonly used elastic fiber staining method Gomori aldehyde magenta method, resorcinol alkaline magenta method, lichen red method, Victoria blue method, ferric iron iodine hematoxylin method, etc. Weigert Elastic Fiber staining solution is mainly composed of resorcinol magenta staining solution and VG Resorcinol alkaline magenta staining solution, etc. Resorcinol alkaline magenta staining solution is mainly used for elastic fiber staining, also known as Weigert resin phenol compound red staining solution, Van Gieson staining method is mainly used for staining collagen fibers, and its staining principle is related to the size of the anionic dye molecule and the penetration of the tissues; the molecular weight of PA is small, followed by Lichun red and compound red, and the molecular weight of light green is the largest; after VG staining, the myofibers are yellow and collagen fibers red.

Weigert elastic fiber staining solution staining principle lies in the resorcinol magenta and iron ions to form Lake complex, its free amino acid and elastic fibers within the hydrogen bonding firmly combined with black, elastic fiber staining can show the changes in the skin tissues of elastic fibers, such as elastic fibers in the nevus, skin ring granuloma, hardness of the disease, etc.; to show and determine the endocardial and arterial lesions, to observe some of the lesions are hit Accompanied by elastic fiber hyperplasia or destruction; can also identify tumor tissue components such as elastic fibroma, after elastic fiber staining, elastic fiber balls can be clearly seen within the tumor, especially suitable for displaying mature elastic fibers.
