It is used in examining the collagen of connective tissue. on formalin-fixed, paraffin-embedded sections, and may be used for frozen sections as well. Smooth muscle tissue, for example, is hard to differentiate from collagen. Also, make sure the slides are not left too long in the decolorizing agent (acid-alcohol). J. Histochem. References. Baby blue = collagen. Masson’s Trichrome Staining) Method was modified from Kiernan (2008). For tissues that are not directly acidic or basic, it can be difficult to use only one stain to reveal the necessary structures of interest. Chichester: Ellis Horwood. This article related to pathology is a stub. Control tissue. In "one-step" methods, all the dyes—with or without a polyacid—are combined in a single solution. May be done with elastin. Should not be confused with Masson trichrome stain. Considered better than the Masson trichrome stain. trichrome stain: staining combinations that usually contain three dyes of contrasting colors selected to stain connective tissue, muscle , cytoplasm , and nuclei in bright colors; generally, tissue sections are first dyed in iron hematoxylin before being treated with the other dyes. Cytochem. The history of the technique is traced from Mallory's aniline blue technique through Masson's trichrome procedure to the techniques of Shorr. Mucin and certain bacteria such as cryptococcus stain deep rose red in this stain, while nuclei are black and other elements are yellow from metanil yellow. Masson's trichrome. MASSON’S TRICHROME Page: 3 of 4 PROCEDURE: 1. Trichrome procedures use three dyes (including an optional nuclear stain). Specifically, Masson's trichrome utilizes three stains to selectively identify muscle, collagen fibers, and fibrin. Trichrome methods are now used for differentiating muscle from collagen, pituitary alpha cells from beta cells, fibrin from collagen, and mitochondria in fresh frozen muscle sections, among other applications. In "yellowsolve" methods, a red dye in dilute acetic acid is first applied, then the section is very thoroughly dehydrated to ensure that no moisture remains. The dyes are used to stain liver biopsies to determine the degree of fibrosis as in cirrhosis as well as kidney biopsies to accentuate the basement membrane and demonstrate immune deposits. 2.
