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

In this study the effect of the A1 agonist 2-chloro-N6-cyclopentyladenosine (CCPA) on bis(1,3-diethylthiobarbituric acid)trimethine oxonol (bisoxonol)-monitored membrane potential in cerebrocortical nerve endings was evaluated. CCPA (30, 100 and 300 microM) caused a dose-dependent decrease of high K(+)- and veratridine-induced membrane

The survival of rat cerebellar granule cells maintained in vitro is enhanced by a KCl-enriched medium. This effect is classically interpreted as resulting from a higher cytosolic calcium concentration. This implies the presence of voltage-dependent Ca2+ channels and a membrane
