Biophysical chemistry, 107(1), 33-49 (2004-02-12)
Non-covalent interactions between polymethine dyes of various types (cationic and anionic thiacarbocyanines as well as anionic oxonols and tetracyanopolymethines) and human serum albumin (HSA) were studied by means of absorption, fluorescence and circular dichroism (CD) spectroscopies. Complexation with the protein

Effects of cyclic AMP on membrane potentials were examined by measuring the changes of bis-oxonol fluorescence in bovine adrenal medullary chromaffin cells. 8-Bromo cyclic AMP (8Br-cAMP) or forskolin caused a gradual and long lasting increase of the fluorescence intensity. The

This study evaluated whether cell membrane depolarization can induce oxidant generation in the isolated perfused rat lung as has been demonstrated with bovine pulmonary artery endothelial cells. Depolarization was produced by perfusing the lungs with high [K+] or with glyburide
P He et al.
Microvascular research, 50(2), 183-198 (1995-09-01)
The membrane potential is an important modulator of calcium ion flux into endothelial cells of venular microvessels. We developed a method to measure the membrane potential of endothelial cells forming the walls of individually perfused microvessels under the same experimental
