Dansylcadaverine (250 mg), AdipoGen Life Sciences. Chemical. CAS: 10121-91-2. Formula: C17H25N3O2S. MW: 335.46. Synthetic. Fluorescent probe for derivatization of aldehydes, ketones and carboxylic acids. Used to prepare small fluorescent biomolecules via amidation or reductive amination. Used to monitor autophagy. Functions by marking the autophagosomes, which allows researchers to follow the molecular components of the process throughout. Accumulates in autophagic vacuoles due to a combination of ion trapping and specific interactions with membrane lipids. Has biological applications in measuring cardiac autophagic flux, studying Parkinson's disease, peritoneal ovarian tumor dissemination and respiratory diseases. This fluorescent tag is preferred over other due to its specificity and simplicity in detecting autophagic vesicles. Spectral Data: ex 335nm; em518 nm in methanol.
