Description

CAS Number: 67-56-1
Chemical Formula: CH₃OH
Molecular Weight: 32.04 g/mol
Synonyms: MeOH, Hydroxymethane, Methyl alcohol, Carbinol
Quality Level: MQ200

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved.

Description

The Giemsa’s Azure Eosin Methylene Blue solution can be used for the staining of blood and bone marrow smears, paraffin sections and clinical-cytological specimens. Giemsa staining is one of the standard procedures in histology, demonstrating various cells with their morphological features better than with H&E stain. The Giemsa stain can also be used to detect Helicobacter pylori in gastric tissue biopsies. The specimen material will show cell nuclei stained in various shades of blue, while other structures will appear in various red types. It is an IVD product and CE registered.

Application

For microscopy. For the staining of blood and bone-marrow smears, paraffin sections and clinical-cytological specimens
