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].

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].

To determine the time course of transglutamination, thymosin β₄ (120 μM) is incubated with Dansylcadaverine (5 mM) in 70 μL buffer consisting of 10 mM Tris-HCl, pH 7.4, 15 mM CaCl₂, 3 mM DTT. The reaction is started by addition of 0.1 U transglutaminase. Immediately after addition of the enzyme (t=0) and at indicated times,10 μL are taken from the mixture, diluted in 490 μL 0.1% TFA to stop the reaction and analyzed by HPLC^[1].

MCF7 cells (2.4×10⁴) are seeded into 35 mm plates. After 24 h incubation, CuO NPs are added with an increasing concentration in the presence or absence of 3-Methyladenine (3-MA) for different time periods . The cells are then incubated with 50 mM Dansylcadaverine (MDC) at 37°C for 15 min and washed with 1×PBS three times with 5 min interval. Finally, the cells are observed under a fluorescence microscope^[2].
