The catalytic effect of vanadium on the pyronine B-H2O2 system is examined. Enhancement of the catalytic reaction rate along with the efficiency and selectivity against vanadium is achieved in a formic acid environment in the presence of a nonionic surfactant

A new simple, selective, high sensitive and rapid method has been developed for spectrophotometric determination of ultra trace amounts of ruthenium based on its catalytic effect on the oxidation of pyronin B by periodate at lambdamax=555 nm. The described method
Apoptotic thymocytes were found to be much dimmer than normal thymocytes when stained with several nucleic acid dyes. These dyes provide a quick and simple assay for apoptosis which works for live cells and does not require a UV laser.

The aim of this work is to analyze the role of specific interactions in host-guest association processes. The formation of inclusion complexes between pyronines Y and B and beta-cyclodextrin and the nature of the interactions involved have been studied using

Inhibition of mitochondrial respiration by hydrophobic fluorescent dyes (Rhodamine 6G, Safranine O, Pyronine B) is much less potentiated by digitonin-lysis of the outer membrane than that by polyamines or adriamycin. This situation may be explained by impermeability of the anion-selective
