Differential staining is a staining process which uses more than one chemical stain using multiple stains can better differentiate between different microorganisms or structures/cellular components of a single organism. Background the laboratory exercise provides instruction on the techniques needed to perform a differential gram stain bacteria can be divided into two groups: gram positive and gram negative. The dye or stain that is used to differentiate one component or cellular structure from another, or to differentiate an entity from another in a specimen it does so by colouring a portion of a specimen (eg of a tissue or of a cell ) that remained uncoloured following the first staining using a dye of different color.

Gram staining is a differential staining technique that differentiates bacteria into two groups: gram-positives and gram-negatives the procedure is based on the ability of microorganisms to retain color of the stains used during the gram stain reaction. The gram stain, developed by christian gram in the 1800’s, was the first differential staining technique in use and is still an important tool for distinguishing between two main types of bacteria—gram-positive and gram-negative. 21 lab 3 bacterial staining techniques ii i differential stains: gram stain and acid-fast stain ii morphological unknown i differential stains.
