Eosin has been used in combination with methylene blue, to detect carboxlic acid group in organic compounds. It gives a red or orange-coloured precipitate on treatment with carboxylic acid solution in water, acetone, alcohol, or dioxin. It is also used as an indicator for differentiation of the colon from the typhoid-dysentery group of bacteria.

Mixture of eosin and methylene blue stains for use in differential microbiological media to culture and identify pathogenic microorganisms, e.g., Neisseria sicca,, Acinetobacter calcoaceticus.
