Giemsa Stain Kit is typically used to identify hematopoietic cells (i.e. mast cells, basophils, polymorphoncuclear leucocytes, etc.) in tissue sections on the Artisan Link and Artisan Link Pro Staining Systems. Although Giemsa stains are frequently used to study bone marrow specimens, this Giemsa Stain Kit is not designed for this application. The tissue elements are stained as follows: Mast cell granules: purple, basophils: purple, eosinophils: bright pink and lymphocytes: blue. This stain is not recommended for cytology specimens or bone marrow smears.
