Beschreibung: Ein einfach zu verwendendes Zwei-Schritte-Kit, das Melanin reduziert und gleichzeitig empfindliches Gewebe, zytologische Details und Antigene bewahrt. Schwere Melaninpigmente in den Zellen können die Zellmorphologie verschleiern und anschließend die Interpretation bei Verwendung routinemäßiger oder spezieller histochemischer Färbungen beeinträchtigen. Das Melanin-Bleichkit ermöglicht die Entfernung von Melanin aus Gewebeschnitten, sodass positive Färbungen richtig interpretiert werden können. Ein Zwei-Schritt-Kit, das kein Mischen erfordert. Wird vor der Färbung verwendet, um Melanin zu reduzieren und gleichzeitig empfindliches Gewebe, zytologische Details und Antigene zu bewahren.

Beschreibung: Sudan Red 7B has been used to stain the fat bodies of Ostrinia nubilalis (Hübner) larvae. Sudan red 7B, also known as fat red, is a non-fluorescent stain.[2] It is effectively used to stain lipids and is used to indicate the presence of suberin in cell walls.[2][3][4] Sudan red 7B acts as a marker for formosan subterranean termite, Coptotermes fornosanus Shiraki.

Beschreibung: Solvent Green 3, also known as Quinizarine Green SS (CI 61565) is an anthraquinone derivative. It is a green dye that imparts its colour to materials. Solvent Green 3 is made by condensing either leucoquinizarin or a mixture of leucoquinizarin and quinizarin with two moles of p-toluidine in the presence of boric acid.

Beschreibung: Lumichrome (7,8-Dimethylalloxazine) is a natural metabolite of riboflavin. It is a flourescent photoproduct of riboflavin degradation. It is known to be an effective photosensitiser and a fluorescent dye. Lumichrome is suitable as a fluorescence probe, metal ion sensor, and may be used for the inactivation of biological contaminants. Its applications are also seen in memory and semiconductor devices.

Beschreibung: Reagent for aluminium. Aurintricarboxylic acid readily polymerises in aqueous solution, forming a stable free radical that inhibits protein-nucleic acid interactions. It is a potent inhibitor of ribonuclease and topoisomerase II by preventing the binding of the nucleic acid to the enzyme. It stimulates tyrosine phosphorylation processes including the Jak2/STAT5 pathway in NB2 lymphoma cells, ErbB4 in neuroblastoma cells, and MAP kinases, Shc proteins, phosphatidylinositide 3-kinase and phospholipase C in PC12 cells. Aurintricarboxylic acid inhibits apoptosis in many cell types. Its neuroprotective effect, perhaps due to its ability to prevent down-regulation of Ca²⁺ impermeable GluR2 receptors or to its ability to inhibit calpain, a Ca²⁺-activated protease that is activated during apoptosis.

Beschreibung: Die Differenzierungslösung besteht aus angesäuertem Ethanol oder Isopropanol, das zum Entfärben von Hämatoxylin-Färbung verwendet wird. Die Dauer der Einwirkung der Lösung bestimmt den Grad der Entfärbung. Die Differenzierung ist ein entscheidender Schritt bei der Hämatoxylin-Eosin-Färbung, um den richtigen Farbkontrast zu erzielen, der für die Visualisierung erforderlich ist, indem überschüssiges Hämatoxylin selektiv aus dem Gewebeschnitt entfernt wird und die gewünschte Färbungsintensität zurückbleibt.

Beschreibung: Methyl green is a synthetic, triphenylmethane-type cationic dye related to ethyl green mainly used as DNA stain in histochemistry. It possesses aniline rings with different degrees of methylation. The dye binds specifically to the A-T rich regions of the major groove of DNA with the help of two positive charges. Methyl green in combination with pyronin is extensively used to stain RNA and plasma cells in tissue sections and cytologic preparations.
