WebDec 28, 2015 · Because the fluorogenic ligand is nonfluorescent by its own and becomes strongly fluorescent only upon binding its cognate tag, unspecific fluorescence background in cells remains minimal even in the presence of an excess of fluorogen, thus ensuring high imaging contrast. WebJun 7, 2013 · Upon binding of the biarsenical molecule to the tetracysteine motif, they start to emit a strong fluorescence signal. Intr oduction of the very small amino acid motif into viral structural proteins by means of genetic modification allowed labeling and subsequent subcellular localization of different types of viruses (reviewed in [ 61 - 68, 90 ]).
WebJan 20, 2014 · Here, we present the development of the first fluorescent assay enabling the measurement of kinetic binding constants for CB1orthosteric ligands. The assay is based on the use of T1117, a fluorescent analogue of AM251. We prove that T1117 binds endogenous and recombinant CB1receptors with nanomolar affinity.
