Introduction
Gram staining a differential staining procedure which stains the gram positive cells with primary stain, the crystal violet which is retained by thicker walled gram positive and gram negative cells are stained with the secondary stain, safranin, as these can not hold the primary stain when decolorizer is applied. Hence appear pink on staining with secondary dye.
