Modulation by Zn2+ of GABA responses in bipolar cells of the mouse retina.
Vis. Neurosci. 17(2) , 273-81, (2000) The localization of endogenous Zn2+ in the mouse retina was examined histochemically and the inhibitory action of Zn2+ on GABA-induced responses was studied in bipolar cells isolated from the mouse retina. Accumulation of endogenous Zn2+ was detected in photo... |

Chelates of cobalt(III) and iron(II) with 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol as test probes for the characterization of chromatographic effects on a reversed-phase liquid chromatography stationary phase.
J. Chromatogr. A. 1099(1-2) , 111-20, (2005) The chromatographic effects on a reversed-phase liquid chromatography (RPLC) phase were established with the use of chelates system: cobalt(III) and iron(II) with 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol as the test probes. Both chelates have the same oc... |

Highly sensitive chelating agents for histochemical staining of rare earth metals.
Histochem. Cell Biol. 112(2) , 179-82, (1999) In tissues, bromopyridylazo-diethylaminophenol has been found to be capable of staining very small amounts of rare earth metals, particularly praseodymium, terbium, dysprosium, holmium, ytterbium, and lutetium. Differentiation of a target metal from interferi... |
