Purpose It is used to stain mast cells in the connective tissue and examine them using light microscopy.
Working Principle Toluidine blue is the unique binding of the dye substance by interacting with the acidic components in the sample. In particular, toluidine blue has metachromasia properties, that is, it has the ability to stain different components in different colors. The chemical structure of the cells, tissue structures or other components in the sample interacts with toluidine blue and allows them to be stained in a certain color.
In this way, toluidine blue staining is used to highlight certain structures in histological or cytological samples and to better visualize them under the microscope. In particular, this staining method is widely used in highlighting connective tissue matrix, mast cells and some other cell types.
