The staining kit LH: Methylene Blue is a valuable tool in food histology and is used to visualize proteinaceous structures, cell nuclei and microorganisms. In food analysis, it is particularly useful for examining fine structures in food samples and identifying potential contaminants.

The special suitability of this kit is achieved by its chemical composition. Methylene blue, a thiazine dye, binds selectively to proteins and DNA, allowing differential observation of cell structures. The dissolved solids in the kit react with the target structures, resulting in intense staining that is visible under the microscope.

At the molecular level, methylene blue binds to negatively charged molecules, particularly phosphates in DNA. This allows detailed visualization of cell nuclei and enables detection of microorganisms.

During application of the staining kit, methylene blue interacts with the target structures and causes a clearly visible staining. This interaction enables detailed visual analysis and contributes to the accuracy and efficiency of food histology.
