  • GRAM STAINING METHOD WITH IMPROVED DECOLORIZATION OF THE CRYSTAL VIOLET-IODINE COMPLEX FROM GRAM NEGATIVE BACTERIA
    Publication number: 20160091401
    Abstract: Provided herein are methods of staining biological material for the purpose of detecting, and in some examples also identifying, microorganisms. Methods of Gram staining bacteria using a slow-acting decolorizing formulation, such as one that includes 1,2-propandiol or ethylene glycol, can be used to extend the time of the decolorizing step, and thus permit automation of the Gram staining method. Also provided are compositions and kits for performing automated Gram staining on microscope slides.
    Type: Application
