| trichrome stain | <technique> Staining combinations which usually contain three dyes of contrasting colours selected to stain connective tissue, muscle, cytoplasm, and nuclei in bright colours; generally, tissue sections are first dyed in iron haematoxylin before being treated with the other dyes.

| Mallory's trichrome stain | <technique> A method especially suitable for studying connective tissue; sections are stained in acid fuchsin, aniline blue-orange G solution, and phosphotungstic acid; fibrils of collagen are blue, fibroglia, neuroglia, and muscle fibres are red, and fibrils of elastin are pink or yellow. Synonym: Mallory's aniline blue stain, Mallory's triple stain. (05 Mar 2000) |
|---|---|
| Masson's trichrome stain | <technique> Original composition for multicolored tissue preparations included Ponceau de xylidine, acid fuchsin, iron alum haematoxylin, and either aniline blue or fast green FCF; chromatin stains black, cytoplasm is in shades of red, granules of eosinophils and mast cells are deep red, erythrocytes are black, elastic fibres are red, and collagen fibres and mucus are dark blue (aniline blue) or green (fast green FCF); modifications substitute other dyes, such as Biebrich scarlet red and wool green stain. (05 Mar 2000) |
| Gomori's one-step trichrome stain | <technique> A connective tissue stain that uses haematoxylin and a dye mixture containing chromotrope 2R and light green or aniline blue; muscle fibres appear red, collagen is green (or blue if aniline blue is used), and nuclei are blue to black. (05 Mar 2000) |
| picro-Mallory trichrome stain | <technique> A modification of Mallory's trichrome stain that involves the addition of picric acid. (05 Mar 2000) |
| MSB trichrome stain | <technique> A stain for fibrin using martius yellow, brilliant crystal scarlet 6R, and soluble blue; fibrin is selectively stained red and connective tissue appears blue. (05 Mar 2000) |
