摘要

Stimulation of cells has so far been observed, among other methods, by the decrease of the intracellular fluorescein fluorescence polarization (IFFP). It is shown that the rate constant of leakage of the fluorescent marker out of the cells increases with stimulation much more significantly than the polarization decreases; thus it might provide a more sensitive method to observe cells stimulation. It is also shown that due to negligible leakage of the marker out of the cells shortly after initiation of the staining of the cell suspension, the fluorescein fluorescence polarization (FFP) of the cell suspension, is very close to IFFP.
