The Gram stain is a differential staining technique most widely applied in all microbiology disciplines laboratories. It is one of the most important criteria in any identification scheme for all types of bacterial isolates. Different mechanisms have been proposed to explain the Gram reaction. There are many physiological differences between Gram-positive and Gram-negative cell walls. Ever since Christian Gram has discovered Gram staining, this process has been extensively investigated and redefined. The Gram staining allows a fast differentiation of bacteria in Gram-positive and Gram-negative. The mureine structure of the bacteria walls is the basis of the color affinity. Bacteria will be stained with Grams crystal violet solution - an aniline dye - in the first step. After the treatment with iod solution, a dye-iod complex will form. During the decolorizing step, this complex stays in the multilayer mureine structures of the Gram-positive bacteria and they will appear blue. Gram-negative bacteria have a monolayer mureine structure only, the dye-iod complex does not stay bound to the cellwall, they will be decolorized. Gram-negative bacteria will be counterstained by safranin solution and appear orange. The Gram Staining Kit All-In-One contains (250 ml each): G0060 Grams crystal violet solution G0061 Grams decolorizer solution G0063 Grams safranin solution G0065 Grams iodine solution - The Gram stain is a differential staining technique most widely applied in all microbiology disciplines laboratories.
