HISTOLOGICAL STAINING PROPERTIES OF PROCION YELLOW M4RS

Histological Staining Properties of Procion Yellow M4rs

Histological staining techniques

The first stainings were tried by A VAN LEEUWENHOEK (apparently in the years 1714-1719) and by R VIEUSSENS (about 1684) studying their objects with alcoholic saffron dyes (LEWIS FT, 1942). At last, genuine histological work began much later when T HARTIG, C WEIGERT, J GERLACH, P EHRLICH and H GIERKE started in the second half of the 19 century with their systematic studies of natural and synthe...

Procion yellow M-4RS binding to neuronal membranes.

Procion Yellow M-4R8, an intracellular neuronal marker, has been shown to bind covalently to the subcellular organelles of rat brain under physiologic conditions. Binding to purified proteins, nucleic acids and lipids also occurs under such conditions, the probable site of attachment being the primary amino group. Lipid membranes were highly impermeable to this dye. The fluorescence intensity o...

Staining of toxoplasma in histological sections.

EXTRACELLULAR toxoplasma, although present in abundance in smears from animals infected experimentally, can only occasionally be found in sections from suspected toxoplasma lesions. In the eye, Wilder (1952a, b) has described organisms morphologically indistinguishable from toxoplasma in cases of granulomatous uveitis, but even in these sections the organisms were not numerous and were found on...

ADSORPTION AND PHOTODEGRADATION OF PROCION YELLOW H-EXL DYES IN TEXTILE WASTEWATER OVER TiO2 SUSPENSION

Removal of a commercial dye (Procion yellow H-EXL) in both synthetic and real wastewater from textile industry over TiO2 suspension has been investigated. The study included both adsorption process (over TiO2) and photocatalytic degradation process in the presence of UV illumination (UV/TiO2). The processes were carried out in aqueous solutions containing the dyes in the presence of titanium di...
