GramstainingProcedure
Gram-staining is a four part procedure which uses certain dyes to make a bacterial cell stand out against against its background. The specimen should be mounted and fixed on a slide before you procede to stain it. The reagents you will need to successfully perform this operation are:Crystal Violet (the Primary Stain) Iodine Solution (the Mordant) Decolorizer (ethanol is a good choice) Safranin (the Cou......閱讀全文
