Färbemittel

Überwinden Sie optische Grenzen, die Ihnen bei mikroskopischen Untersuchungen natürlicherweise gesetzt werden, indem Sie bestimmte Strukturen mit Färbemitteln und Reagenzien hervorheben, und schützen Sie die Proben anschließend mit Fixiermitteln. Die schnell wirksamen Farbstoffe sorgen für starke Kontraste zwischen Zellbestandteilen, um die Detektion oder Analyse zu erleichtern. Die angebotenen Färbemittel unterscheiden sich in ihrer sensitiven Affinität zu bestimmten Komponenten von Organellen oder Zellen, sodass diese genau auf die jeweilige Untersuchung abgestimmt werden können. Die Arbeit mit den flexibel einsetzbaren, gebrauchsfertigen Färbemitteln kann manuell oder mithilfe von automatischen Geräten erfolgen.

Differenzierungslösung

Supplier: SIGMA ALDRICH MICROSCOPY

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.
