Paper Abstract

Microspectrofluorometry and fluorescence imaging have been largely used to measure the intracellular pH of living cells. Such in vivo measurements require the knowledge of the optical properties of the tissue and the pharmacokinetic of the dye. The purpose of this study was to investigate in vitro and in vivo spectral characteristics of BCECF. In vitro, measurements in presence of blood show that blood content can greatly affect pH measurement by increasing the fluorescence ratio. In vivo, the presence of blood in high vascularized tissue leads to the modification of BCECF spectral characteristics. Fluorescence kinetic profiles provides information about tissue perfusion. Consequently, pH measurements using BCECF or fluorescein derivatives by the double excitation method may be performed taking in account the tissue blood content and the tissue pharmacokinetic of the dye.
