Product Introduction:

Narrowly defined, connective tissue staining refers to the distinguishing staining between the three types of fibers, namely collagen fibers, reticular fibers, elastic fibers, or distinguishing staining between them and other tissues. Masson trichrome staining is the most classic method of staining connective tissue. The so-called trichrome staining usually refers to staining the cell nucleus and selectively displaying collagen fibers and muscle fibers. The dyeing principle of this method is related to the size of anionic dye molecules and the penetration of tissues: the size of molecules is reflected by their molecular weight. Small molecular weight dyes are easy to penetrate tissues with dense structures and low permeability, while large molecular weight dyes can only enter tissues with loose structures and high permeability.
The difference between the G1346-Modified Masson's Trichrome Stain Kit and the G1340-Masson's Trichrome Stain Kit lies in the addition of a mordant solution (free of picric acid and odorless). After pre-treatment with the mordant solution, collagen fibers are colored better and less prone to over staining. Additionally, the cell nucleus is lightly stained with Celestite Blue Hematoxylin Solution for clearer and more stable comparison. This kit is suitable for staining tissue paraffin sections, frozen sections, and other tissues.
