[交流] 有谁知道Masson‘s trichrome stain即masson三色染色、马氏三色染色法的原理和意义。

我想要知道masson三色染色的原理和意义、主要是用在什么实验当中。谢谢大家。

Masson’s trichrome染色,主要用于区别胶原纤维与其他组织,常用于如肝硬化等实验动物模式。
原理、方法等见附件
Principle
Trichrome procedures are so named because three dyes, which may or may not include the
nuclear stain, are used. Sections are first stained with an acid dye such as Biebrich scarlet.
All acidophilic tissue elements such as cytoplasm, muscle and collagen will bind with the
acid dyes. The sections are then treated with phosphotungstic and/or phosphomolybdic acid.
Because cytoplasm is much less permeable than collagen the phosphotungstic and
phosphomolybdic acids cause the Biebrich scarlet to diffuse out of the collagen but not out of
the cytoplasm. Phosphotungstic and phosphomolybdic acids have numerous acidic groups
that most likely act as a link between the decolorized collagen and aniline blue, the collagen
dye. Probably the pH of the phosphotungstic/phosphomolybdic acid solution also increases
selective collagen staining and aids in the diffusion or removal of Biebrich scarlet.
