摘要:
The present invention describes the use of a fluorescent NIR dye for various applications by simply changing the solvent conditions. Molecule of formula 1 in the monomeric state (30 % ACN / 25 mM phosphate buffer) can be used for the sensitive detection of thiols and monitoring minor fluctuations in the thiol concentration inside live cells. Molecule 1 in the self-assembled state (25 mM phosphate buffer) can be used for labeling of serum albumin protein either covalently or noncovalently at specific pH. The probe 1 specifically bind with the serum albumin proteins noncovalently at lower pH gives a "turn-on" NIR emission whereas it binds covalently at higher pH gives a "turn- on" green fluorescence. Since the probe detects serum albumin proteins selectively in presence of other thiol containing small molecules, the probe can be used as an excellent sensor for serum albumin proteins. The dye-protein complex of various ratios can be used as sensors to detect the pH variations in a broad window from 4.6 - 11.6 with high sensitivity. Due to the high biocompatibility and water solubility the dye protein complex is useful for ratiometric detection of minor pH variations inside cellular environment.
