Routine and special histochemical stains | Histopathology | VBCF Until then, I guess some people will use Picrosirius Red & polarizing microscopy to analyse Collagen types as recently: e.g. Sirius red is a strong cationic dye which stains collagen by reacting via sulfonic acid groups with basic groups present in the collagen molecules. Due to the excellent differentiation of collagen, elastic, fibrin and muscle fibers, the Movat can reveal subtle changes that the routine and normal special stains do not. The elongated dye molecules are attached to collagen fibers in such a way that their long axis is parallel. Special Stains available include: 1. Safranine O/ fast green staining and Sirius red also can be used and you can quantitative estimation of collagen synthesis is also a method. 9. 4.2.2.

Principle of the stain: • Collagen and muscle fibers are demonstrated using a tungsten mordant provided by the phosphotungstic acid. Sort by. Although there are numerous special stains for identification of elastic fibers, VVG is most commonly used because it is quick, and produces intense staining of elastic fibers. A number of other stains are used in the staining of most liver tissues.
In drug discovery research, quantitative evaluation of the collagen fibers is required, so it is necessary to be able to distinguish between collagen fiber typesⅠand III. MT is a special stain which offers a simultaneous contrast color to the collagen fibers along with muscle fibers facilitating better visual discrimination between them.8 Collagen is the major structural element of the connective tissue which contributes to the stability and maintains structural integrity. Special stains are performed on sections of control tissue known to contain components specific to each special stain.
