General description

Gallocyanine belongs to the oxazine class of dyes. It is synthesised from methanol solution of gallic acid in the presence of excess iodine. Gallocyanine is used to stain animal cells, mostly the nucleic acids. It also acts as a chelating agent and is used to determine bioactive compounds and several metal ions.

It is suggested that a nuclear stain; gallocyanine, be used simultaneously with the three main histological staining methods: hematoxylin-eosin, Van-Gieson's, and Nissl' stainings. This modification is technically simple, gives preparations of a high quality, and is time- and labour-saving.
