Another common variant is the Masson trichrome & Verhoeff stain, which combines the Masson trichrome stain and Verhoeff's stain. Masson trichrome stain (principle of the technique) The mechanism of the stain is not totally understood, and may be related to the size of different dye molecules. on formalin-fixed, paraffin-embedded sections, and may be used for frozen sections as well. The general rule in trichrome staining is that the less porous tissues are coloured by the smallest dye molecules, and whenever a dye of larger molecular size is able to penetrate it, it will always do so at the expense of the smaller molecules. The Gomori-trichrome method is used for other tissues because it is easier to perform and provides equally satisfactory staining of collagen and muscle. Of the various types of trichrome stains available, those most commonly used today are: Masson’s Trichrome: This is a multi-step staining technique. It is very sensitive, hence it is able to detect small protozoans missed during we mount examination. Various trichrome recipes exist, all of which arose from pathologist Claude L. Pierre Masson’s original formulation from the early 1900s. METHOD: Fixation: Formalin 10%, Phosphate Buffered . 1‘‘Trichrome’’ stains are used primarily for distinguishing collagen from muscle tissue. Component To make 50 mL To make 75 mL To make 250 mL .

Hello everyone, I have been trying Masson's Trichrome Staining on Myf5 skeletal muscle sections. PRINCIPLE: Verhoff’s Hematoxylin stains the elastic fibers, and a modified Masson’s Trichrome is used to stain the other connective tissue elements. The purpose of this stain is to differentiate between collagen & muscle. Let’s take a look at the staining components and how they affect the stain. Masson Trichrome & Verhoeff Stain. … Watch our new video on Masson's Trichrome Staining Protocol for Collagen Fibers. References: Masson, P.J. Stain penetration of the microsporidial spore is quite difficult; therefore, the dye content of the chromotrope 2R in the stain formula is 10 times that normally used in the Wheatley’s modification of Gomori’s trichrome stain for intestinal protozoa. Methods 12:75-90, 1929. Masson's trichrome is a classical method of visualization with several variants. The general rule in trichrome staining is that the less porous tissues are colored by the smallest dye molecule; whenever a dye of large molecular size is able to penetrate, it will always do so at the expense of the smaller molecule.
