Overview

Hematoxylin is a widely used biological staining dye employed in histology, cytology, and laboratory research for the visualization of cellular and tissue structures. After oxidation to hematein and complexing with a suitable mordant, hematoxylin selectively stains nuclear material, producing strong contrast under microscopic examination.

It is commonly used as a primary nuclear stain and is compatible with a variety of standard staining formulations, including Harris, Mayer’s, and Gill’s hematoxylin preparations.

Typical Applications

• Histological tissue staining

• Cytological specimen staining

• Nuclear visualization in microscopy

• Educational and research laboratory use

• Preparation of custom hematoxylin staining solutions

Key Features

• Strong affinity for nuclear components

• Produces clear, high-contrast staining

• Suitable for multiple hematoxylin formulations

Preparation Notes

Hematoxylin requires oxidation to hematein before use and is typically combined with a mordant (e.g., alum) to achieve optimal staining performance. Preparation methods may vary depending on the intended staining protocol.
