These cells do not absorb bone marrow stains and stain positive for cytokeratin, a protein normally found in the lining of the breast and colon.

The whole cell will eventually stain uniformly with eosin after karyolysis.

The cells stain Gram positive, although its cell envelope is unusual and is reminiscent of the cell walls of Gram negative bacteria.

If staining is carried out after disaggregation all cells stain but two phenotypes, one polar and one non-polar, can be distinguished.

See the cells stained bright pink?

The glandular and ductal cells of the salivary glands stained strongly for EGF.

Metaplastic cells often stain both green and pink at once.

The young cells will generally stain gray or blue in the cytoplasm, while the nucleus stains purple.

Polychromatic cells usually stain dark blue or gray and are distinguishable from normal blood cells mostly by a slight change in color.

Almost all cells readily stain with a number of basic dyes due to the electrostatic attraction between negatively charged cellular molecules and the positive charge on the dye.
