  Abstract:

  Real-time in-cell 19FNMR spectroscopy is developed   to determine the time scale of cellular uptake of   fluorescent and

  nonfluorescent 19F-octaarginines. The peptide   concentration as low as 10-mM order is   successfully detected with a

  time resolution of 1–2 min. The concentration analysis shows   that fluorescein isothiocyanate (FITC) induces different

  kinetics for the peptide uptake into natural human cells.   The ability of 19FNMR to detect the real-time uptake of   bioactive

  molecules is shown with minimal perturbation.
