| Application: | Neutral red has been used in several histological staining applications that include:• as a nuclear stain • as a counterstain in the Gram procedure, either alone, or as a component of the Twort stain, a fast green-neutral red mixture. • fluorescent staining of nucleic acids in nervous tissue, of lipids and hydrophobic substances such as suberin and of phenolic compounds in algal cell walls • detection of viable yeast cells in dandruff samples and of mussel larvae • Neutral red has also been used as a stain in flow cytometry. |
| Application: | Useful as an indicator for preparing neutral red paper, and as a biological stain. |
