Wheatley Trichrome Stain is a multi-component staining solution used for the differential visualization of intestinal protozoa in preserved stool specimens. Based on the modified Gomori trichrome method, this formulation provides clear contrast between protozoan cytoplasm, nuclei, and background debris, supporting accurate microscopic evaluation. The stain produces consistent color differentiation to aid in the identification of trophozoites and cyst forms. Suitable for use in clinical, veterinary, and research laboratories, Wheatley Trichrome is compatible with standard fixation and staining protocols and is intended for routine parasitology applications.
