Overview

Product Introduction

Trypan Blue is an azo based, hydrophilic, tetrasulfonated blue acid dye widely utilized for assessing cell viability. As an easy method to determining the viability of cells, Trypan Blue will stain dead cells with permeable membranes blue, while the dye is excluded by most living cells and their intact membranes thereby allowing visual determination of living versus dead cells. Although Trypan Blue is predominately used for assessing cell viability of cultured cells, other applications for this dye have been reported. In rat abdominal organ slices Trypan Blue has been utilized to determine cell viability as well as islet cell cluster cell viability from caprine pancreatic samples.
A viability dye for quantifying live versus dead cells

The trypan blue dye is an azo dye, derived from toluidine. It is soluble in water and has a molecular weight of 961 g/mol.

Application

Trypan blue has been used:

in cell viability assay

to determine the number of living and necrotic cells by staining with 0.2% trypan blue solution.

to stain plant tissue in order to to visualize cell death

Biochemical and Physiological Mechanisms

The trypan blue dye is useful to differentiate the dead and live cells based on the cell′s ability to take up or exclude the dye. A viable cell is assumed to possess an intact cell membrane and hence excludes this dye and the cytoplasm appears clear. Whil
