Description
This dye has been used in histology only rarely. Lendrum, Slidders, and Fraser recommended it for their standardized trichrome method, considering it to be a suitable plasma stain after silver impregnations.
It should be noted that it is not related to eosin, although it is an azo dye. The name presumably reflects a similarity in color.
