Dansylcadaverine (Monodansyl cadaverine) 是一种用于标记自噬空泡的自荧光化合物。Dansylcadaverine 是谷氨酰胺转胺酶的高亲和力底物，能阻断受体介导的多种配体的内吞作用。
| 生物活性 | Dansylcadaverine (Monodansyl cadaverine) is an autofluorescent compound used for the labeling of autophagic vacuoles. Dansylcadaverine, a high affinity substrate of transglutaminases, can block the receptor-mediated endocytosis of many ligands[1][2]. |
体外研究
(In Vitro) | The inhibitory activity of dansylcadaverine reflects its ability to serve as a substrate for transglutaminases and to block competitively the crosslinking of fibrin molecules[2].
Dansylcadaverine, a cationic fluorescent probe binds to bacterial lipopolysaccharide and lipid A, and is displaced competitively by other compounds which possess affinity toward endotoxins[3].

| 染色示例 | Description: Dansylcadaverine is an acid dye with green fluorescence, it is a specific marker for autophagic vacuoles, and it can be used for the detection and quantification of autophagy.Method: For Dansylcadaverine staining.1. Cells are seeded in 6-well plates at a concentration of 3×104cells/well in a 5% CO2incubator at 37℃ for 24 h.2. Following transfection, 50 mM Dansylcadaverine is added to each well for 15 min incubation, and then rinse cells for 3 times with PBS.3. The fluorescence is visualized under a confocal laser-scanning microscope (TCS 4D; Leica, Heidelberg, Germany). Description: Dansylcadaverine is an acid dye with green fluorescence, it can be used as a specific autophagolysosome marker to analyze the autophagic process.Method: For Dansylcadaverine staining.1. Cells are cultured on confocal dishes at a density of 1×104cells/mL overnight and then added with testing compounds for one hour.2. After stimulation with RANKL (50 ng/mL) for five days, cells are incubated with Dansylcadaverine (50 mM; 15 min; 37℃).3. Wash cells with 1×PBS for three times with 5 min interval.4. Finally, the cells are observed under a confocal laser scanning microscopy.
