Sizemore, RK , Caldwell, JJ and Kendrick, AS (1990) Alternate gram staining technique using a fluorescent lectin. Appl. Environ. Microbiol. 56:2245-7

Abstract

Fluorescence-labeled wheat germ agglutinin binds specifically to N-acetylglucosamine in the outer peptidoglycan layer of gram-positive bacteria. The peptidoglycan layer of gram-negative bacteria is covered by a membrane and is not labeled by the lectin. By exploiting this phenomenon, an alternative Gram staining technique has been developed.
