Cyanide-sensitive fluorescent probes
We characterize the response of several boronic acid containing fluorophores, which are widely used for sugar determination, towards aqueous cyanide. In two recent reports we have shown that boronic acid containing fluorophores can be used to sense aqueous cyanide through physiological safeguard levels. In this report we show that our new sensing mechanism is not just specific to our recently r...
متن کاملStrategies for Developing pH Sensitive Fluorescent Probes
Many physiological processes function efficiently within a well-controlled pH range. Higher acidity level has been implicated with a number of systemic pathologies. The potential of pH sensitive fluorescent probes for reporting on biological environments has been widely utilized in a variety of cell studies and has been recently recognized as a powerful technique for in vivo imaging of diseases...
متن کاملHydrolysis of Ca2+-sensitive fluorescent probes by perfused rat heart.
Rat hearts were loaded with the fluorescent calcium indicators fura 2, indo 1, rhod 2, or fluo 3 to determine cytosolic calcium levels in the perfused rat heart. With fura 2, however, basal tissue fluorescence increased above anticipated levels, suggesting accumulation of intermediates of fura 2-AM deesterification. To examine this process, we separated the intermediates of the deesterification...
متن کاملAnalysis of protein folding using polarity-sensitive fluorescent probes
Polarity-sensitive fluorescent probes like 8-anilino-1naphthalenesulphonate (ANS) and 1,1′-bis(4-anilino5-naphthalenesulphonic acid (bis-ANS) have been frequently used to detect equilibrium folding intermediates like the molten globule state, as the formation of the latter involves increase in hydrophobic exposure. The ability of these fluorescent probes to bind to the intermediate state thus p...
