approach to a multimodal imaging reagent for peptidelabellingvia disulfide bridging. The reagent is constructed using a one pot, three component, [3 + 2] cycloaddition of a fluorescent azide with a dithiomaleimide-alkyne, with concomitant incorporation of 125I. The dithiomaleimide handle then enables site selective conjugation to a disulfide bond of a peptide whilst retaining the key structural bridging
Lighten up: A selective fluorescent‐labelingagent for quorum sensing (FLAQS) can be used for the visualization of the communication pathway of bacteria in livecells (see figure). This represents a new, operationally simple, fast, and inexpensive tool for the imaging of quorum‐sensing receptors by using fluorescentlylabeled signaling‐molecule analogues.
