Description

Mayer'S Hemalum CAS NO 81178-28-1 is a specialized histological staining reagent, a complex of aluminum and hematein, widely recognized for its critical role in nuclear staining. This product is essential for achieving high-contrast, precise visualization of cell nuclei in tissue sections, a fundamental step in pathological diagnosis and biological research. It is a key component for laboratories in the histology, pathology, cytology, and life sciences sectors, where reliable and consistent staining results are paramount for accurate analysis.

Application

Mayer'S Hemalum is a cornerstone reagent in microscopic analysis, primarily used for:

• Nuclear Staining in Histology: As the primary stain in Hematoxylin and Eosin (H&E) procedures to clearly delineate cell nuclei in blue or purple.
• Pathological Diagnosis: Enabling pathologists to examine tissue architecture and identify abnormalities in biopsy and surgical specimens.
• Cytological Preparations: Staining nuclei in Pap smears and other cytology samples for cancer screening and diagnosis.
• Botanical and Zoological Microtechnique: For studying cellular details in plant and animal tissue sections.
• Immunohistochemistry (IHC) Counterstaining: Providing nuclear contrast after chromogen development to localize specific antigens.
• Educational and Research Laboratories: Used in academic settings for teaching histology and conducting basic life science research.
