Abstract: A new kind of glycolipid bearing p-aminophenyl-α-D-mannopyranoside was synthesized and the direct visual observation of sulforhodamine-labeled concanavallin Abound to the glycolipid monolayer was achieved by using a speciaily designed miniaturized Langmuir trough On the stage of fluorescence microscopy. The glycolipid was spread at a gas phase,and concanavallin Awas injected into the subphase. After incubation for 20 min in 20℃,niany large regular concanavallin Adomains(μm level) were observed for the first time. No regular protein domain was found when the dead concanavallin Ainjected,this indicates that the specific interaction between glycolipid and the protein is responsible for the formation of protein domains.
