Descripción

General description

Assay measures the increased activity of cellular mitochondrial dehydrogenases that can cleave the tetrazolium dye WST-1 to formazan. The formazan formation is then quantified by measuring the change in absorbance at 450 nm in a microplate reader. The activity of mitochondrial dehydrogenases is proportional to cell number. No washing, harvesting, or solubilization steps are required.

Features and Benefits

Sensitivity: 1000 cells (adherent); 2500 cells (nonadherent)

Components

WST-1, 1-Methoxy PMS, and a user protocol.

Warning

Toxicity: Multiple Toxicity Values, refer to MSDS (O)

Specifications

Assay Time: 0.5 - 4 h

Principle

The Calbiochem Rapid Cell Proliferation Kit is designed to determine the number of viable cells in proliferation, or cytotoxicity studies, based on the cleavage of the tetrazolium salt WST-1 by mitochondrial dehydrogenases in viable cells. The assay can be used to measure cell proliferation in response to growth factors or cytokines, or to assess cytotoxic compounds.

Preparation Note

• WST-1 Labeling Mixture: Thaw the EMS solution at room temperature or in a 37°C water bath. Add the entire contents of this solution to the bottle containing the WST-1 reagent. The mixed solution can be stored at 4°C for several weeks. For long-term storage (several months) aliquot and store at -20°C. Protect from light.
