GANGLIOSIDE HAVING FLUORESCENCE-LABELLED CERAMIDE PORTION AND PROCESS FOR PRODUCING THE SAME

摘要

A ganglioside having a fluorescence-labelled ceramide portion and represented by general formula (I), wherein -O-R-O- represents a sugar chain constituting a ganglioside; R' represents an ether, sulfide, amide, urethane, thiourea or amino group having a fluorescent dye; one of R<5> and R<6> represents a single bond and the other represents hydrogen; 1 represents an integer of 1 to 8; m represents an integer of 2 or above; and n represents an integer of 0 to 12. This derivative, having the recognition characteristics of the sugar chain portion thereof and the labelling function of the fluorescent dye introduced into the ceramide portion, is utilizable as a reagent which can trace dynamic behaviors of glycolipid receptors, a reagent for laboratory diagnosis of bacteria and viruses, and so forth.
