Giemsa's Stain

Giemsa's Stain is a histological dye used for the differential staining of blood cells and parasites. The product is identified by CAS No. 51811‑82‑6 and is supplied as a clear solution with a solubility of 0.1 % in methanol. Spectrophotometric data show two absorption maxima, one between 640 nm and 650 nm and a second between 520 nm and 525 nm. The absorptivity values range from 950 to 1150 A¹%·cm⁻¹ at the first maximum and 600 to 750 A¹%·cm⁻¹ at the second maximum.

In laboratory practice the stain is typically prepared at a 1 % w/v concentration for routine blood smears. It is stored in tightly sealed containers to protect against moisture, with a recommended storage temperature of 2‑8 °C to preserve colour stability. The dye complies with common laboratory reagent standards and is often used alongside buffer solutions such as phosphate‑buffered saline. Typical packaging is an amber‑coloured glass bottle that shields the solution from light degradation.

The stain is primarily purchased by pathology laboratories, research institutes and teaching hospitals that require reliable cell morphology visualization.
