Description

Application

Neutral red has been used as a staining agent for micro- and meso-plankton. It has been used as a staining agent for nematocytes.

Useful as an indicator for preparing neutral red paper, and as a biological stain.

Actions biochimiques/physiologiques

Neutral red is useful as an indicator for preparing neutral red paper, and as a biological stain. Neutral dye has low toxicity and is a vital dye. It can also be used as a pH indicator. It is used for cell viability assay. The dye accumulates in the lysosomes of living healthy cells, but not in damaged cells.

Adéquation

Certified for use in the method of Doan & Ralph for the supravital staining of living blood cells.
