Graphical Abstract

Viele Säugetier-Glycane, die mit Signalrezeptoren assoziiert sind, enthalten N-Acetyllactosamin an der letzten oder vorletzten Position. Eine hochspezifische Methode zur Markierung dieses Disaccharids auf Zelloberflächen-Glycoproteinen lebender, kultivierter Zellen und Zebrafischembryos nutzt einen zweistufigen chemoenzymatischen Ansatz aus In-situ-Fucosylierung und bioorthogonaler Klickreaktion (siehe Schema; α(1,3)FucT=α(1,3)-Fucosyltransferase).
