6-十二酰基-N,N-二甲基-2-萘胺

Laurdan (6-Dodecanoyl-2-Dimethylaminonaphthalene) is an organic compound which is used as a fluorescent dye when applied to fluorescence microscopy. It is used to investigate membrane qualities of the phospholipid bilayers of cell membranes. One of its most important characteristics is its sensitivity to membrane phase transitions as well as other alterations to membrane fluidity such as the penetration of water.
