Beschreibung: Osmium tetroxide is also referred to as osmium and is mainly used as a secondary fixative of tissues. The molecule reacts with lipid moieties and is responsible for the oxidation of unsaturated bonds of fatty acids. This reaction adds density and contrast to biological samples. In normal tissues, presence of osmium results in intense black staining which can be viewed by normal eye. In addition, it can be used as a mordant (a molecule which combines with stain or dye at later stages) in electron microscopy, thereby enhancing lead staining.

Beschreibung: o-Tolidine is a diacidic dye which is sparingly soluble in water and easily soluble in ether and alcohol. On exposure to chlorine or bromine vapors, it forms an intense blue color. This forms the basis for detection of chlorine, nitrates and hydrogen peroxide in air or water. It turns yellow on reacting with free chlorine. o-Tolidine easily forms acid salts.

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.
