Masson Trichrome Kit

Connective Tissue Stain โ€” Collagen Differentiation

Connective Tissue Kit

Masson Trichrome Kit

ISO-Compliant Histopathology Grade โ€” Supplied by Delonix Enterprise

Masson's Trichrome is the most widely used connective tissue stain in histopathology. This three-dye technique differentially stains collagen fibers, muscle, cytoplasm, and nuclei in distinct colors. Collagen stains blue or green (depending on formulation), cytoplasm and muscle stain red or pink, and nuclei stain dark brown or black. Essential for evaluating fibrosis in liver biopsies, studying renal pathology, diagnosing muscular dystrophy, and assessing cardiac tissue changes. The clear differentiation makes it invaluable for quantifying collagen deposition in chronic diseases.

Stain Type
Trichrome (Three-dye)

๐Ÿ’ก Standard for assessing hepatic fibrosis staging and cirrhosis evaluation. Also used to differentiate between collagen (blue/green) and smooth muscle (red) in gastrointestinal and cardiovascular pathology.
Staining Characteristics

Masson Trichrome Results

1

Collagen Fibers

Stain blue (aniline blue formulation) or green (light green formulation). Type I and III collagen clearly visible.

2

Cytoplasm & Muscle

Stain red with Biebrich scarlet or acid fuchsin. Distinguishes muscle from connective tissue.

3

Nuclei

Stain dark brown to black with Weigert's iron hematoxylin. Chromatin detail preserved.

4

Fibrin

Stains bright red, useful for identifying thrombi and fibrin deposits in tissue sections.
