- Finest Control of the Ripening Process
- Longest Shelf Life
- Fewest Artifacts
- Reproducible Vibrant Staining
The most commonly used histological stain, hematoxylin is a natural compound extracted from a species of tree found in Mexico and the West Indies. The extracted compound is oxidized to produce hematein, the active staining component of the hematoxylin stain. The production of histological staining solutions is an art. Only a few laboratories are capable of developing a stain of reliable vibrance.
At National Diagnostics we have gone one step further. Our proprietary methods achieve the finest control of the ripening process,resulting in the only commercially available Harris’ Hematoxylin with a full one year shelf-life.
