Application

In Vitro Toxicology Assay Kit, Sulforhodamine B based has been used for spectrophotometric measurement of biomass (viable and non-viable cells) by total protein. It has also been used to study the effect of 17-allylamino-17-demethoxygeldanamycin (17-AAG) on proliferation of the five uveal melanoma cell lines. Absorbance of dye is measured at a wavelength of 565nm.

Biochem/physiol Actions

Dye binds to cellular protein and is then solubilized in base.

General description

The Sulforhodamine B method is simple, accurate, and provides consistent results. This assay system is a means of measuring total biomass by staining cellular proteins with sulforhodamine B.
