m-Methyl red is a commonly used tissue stain, widely used in medical research, histology and biological experiments. It belongs to the basic dye, its molecular structure contains benzene ring and methylene, so that it has a strong color and high dyeing ability. In histology,m-methyl red is widely used to stain the nucleus and collagen fibers, which can clearly show the structure of cells and tissues, providing a powerful tool for scientists to study the morphology and structure of cell tissues.

m-Methyl red is one of the commonly used dyes in tissue section dyeing. By methyl red staining, the nucleus and collagen fibers in the section can be dyed red or pink, making the structure of cells and tissues more obvious and clear. This will help students and researchers to better observe and understand the structure, function and related pathological changes of tissues.
