Disclosed herein are compositions for assessing peptidoglycan biosynthesis in bacteria using modified dipeptides containing a bioorthogonal tag and applying novel post-labeling methods to label the bioorthogonal tag. The resultant, labeled peptidoglycan structures are amenable for identifying bacteria by microscopic visualization.

Maleinimides are widely used to label proteins and to derivatize thiols. The so-called click reaction was shown to allow the efficient introduction of the maleinimido group into azido-modified fluorophores (benzoxazines) by reacting them with an alkyne-modified maleinimide to yield new thiol-reactive fluorescent labels 5–7. The reaction proceeds under mild experimental conditions and provides a new

The invention relates to a method for detecting the proportion of Gram-positive and Gram-negative bacteria in a complex sample. The bacteria are detected according to the Gram signal thereof. The invention enables distinction between species of Gram-positive bacteria and species of Gram-negative bacteria in a complex sample. The invention also relates to a kit for marking Gram-positive and Gram-negative bacteria, particularly for use in flow cytometry, particularly for complex samples such as human or animal microbiota samples.
