Product Description

General description

Neutral red (C.I. 50040) is a protonated diaminophenazine dye. It is aminodimethylaminomethylphenazinehydrochloride, C15H17N4Cl.

Application

Neutral red has multiple staining applications that include its use as a nuclear stain, counterstain in the Gram procedure, either alone, or as a component of the Twort stain (a fast green-neutral red mixture). Neutral red staining is also a viability assessment method used for the detection of viable yeast cells in dandruff samples and of mussel larvae. Neutral red is also recommended for use in viability assessment as it is selectively absorbed by lysosomes and other acidic organelles in cells. It is also used for supravital staining of living blood cells.
Useful as an indicator for preparing neutral red paper, and as a biological stain.

Biochem/physiol Actions

Neutral red is a widely used cationic fluorochrome that is known to accumulate in the Golgi complex and nuclei after first staining lysosomes.

Chemical Properties dark green powder
Uses Neutral Red is a common histology stain used to determine cell viability.Dyes and metabolites.
Uses Can be used as a vital stain, to stain living cells.
Uses Neutral Red is used as indicator for nitrogen determination; pH indicator.
Application Transition of pH Indicator: pH 6.8 - 8.0, red to yellow. Basic red 5 is a dye used in histology for staining nuclei. It is also a pH indicator. As such it is used in microbial culture media for differentation of bacteria. For example MacConkey agar contains it and lactose. Acidification by lactic acid turns on the Basic red 5. Therefore, colonies formed by bacteria that ferment lactose into lactic acid will turn red and stand out from the pale colonies of non-lactose-fermenting bacteria. Basic red 5 is also used in cell viability tests based on the ability to incorporate and bind it.
Preparation (a) N,N-dimethyl-4-nitrosobenzenamine?and 4-Methylbenzene-1,3-diamine???reaction, form Toluylene Blue (Basic Dye, C.I. 49410), heating make cyclization; (b) oxidation N1,N1-dimethylbenzene-1,4-diamine?, and 4-Methylbenzene-1,3-diamine mixture.
