Leishman Stain is a widely used reagent in hematology and microbiology laboratories for the detailed visualization of blood cells and intracellular parasites, such as Plasmodium sp., the causative agent of malaria, among others.

Like other Romanowsky-type stains—such as Giemsa, Wright, and May-Grünwald—Leishman stain combines methylene blue derivatives with eosin. This combination enables clear differentiation of cellular structures:

• Methylene blue stains structures such as the cell nucleus and intracellular parasites, producing blue-purple tones.
• Eosin stains components like the cytoplasm, giving a reddish or pink coloration.

Thanks to this contrast, Leishman stain provides sharp and well-defined images under the microscope, facilitating clinical diagnosis and research.

Ideal for clinical laboratories, research centers, and educational settings that require a fast, effective, and high-quality staining method.
