Staining of Microorganism
Dyes are used in microscopy whenever microorganisms, cell and tissue components in animal and plant material have to be visualised. In order to make microorganisms suitable for microscopic staining, they have to be fixed and stained with suitable dyes. Gram-staining, spore staining and the detection of mycobacteria are of particular importance. Merck offers a broad range of products for fixing and staining of microorganisms, which includes universal reagents and dyes.
