Leishman's stain, also Leishman stain, is used in microscopy for staining blood smears. It provides excellent stain quality. It is based on a methanolic mixture of "polychromed" methylene blue (i.e. demethylated into various azures) and eosin.


The methanolic stock solution is stable and also serves the purpose of directly fixing the smear eliminating a prefixing step. If a working solution is made by dilution with an aqueous buffer the resulting mixture is very unstable and cannot be used for long. Leishman stain is a Romanowsky-type dye, similar to Wright stain.


Leishman's Stain is used generally in hematology and tropical medicine to differentiate and identify leucocytes, malarial parasites and trypanosomes. .


Soluble in water (4 mg/ml), ethanol (4 mg/ml), in 0,1% methanol (clear, blue soln with fluorescence) or methyl cellosolve (20 mg/ml).
