      Description
      OverviewAssay 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.

      Intended useThe 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.
      BackgroundCell proliferation assays are widely used in cell biology to study growth factors, cytokines, and media components, to screen cytotoxic agents, and for lymphocyte activation. The use of tetrazolium salts such as MTT commenced in the 1950s, and is based on the fact that live cells reduce tetrazolium salts into colored formazan compounds. The biochemical procedure is based on the activity of mitochondrial enzymes, which are inactivated shortly after cell death. The new cell proliferation reagent WST-1 has several advantages as compared to MTT. WST-1 yields water-soluble cleavage products like XTT, which can be measured without an additional solubilization step, and WST-1 has a wider range than MTT or XTT.
      Principles of the assayThe Calbiochem® Rapid Cell Proliferation Kit provides a colorimetric assay for the fast and convenient determination of viable cell numbers in cell proliferation and cell cytotoxicity assays. After mixing the two components supplied in the kit the mixed solution is added to the wells of a 96-well plate (tissue culture plate) that contains cultivated cells. The intensity of the dye is proportional to the number of viable cells and the absorbance is read with a microplate reader at 440-460 nm after a 0.5-4 h incubation at 37°C.
      Materials provided• WST-1 Reagent (Kit Component No. JA7700-1EA): 1 vial, supplied as a powder in an amber glass bottle
      • Electron Mediator Solution (EMS) (Kit Component No. JA7701-5ML): 1 vial, 5 ml in an amber glass bottle
      Materials Required but not provided• Pipettors with disposable tips
      • Tissue culture grade, flat-bottom 96-well plate
      • Spectrophotometer capable of measuring absorbance in 96-well plates at a wavelength of 440-460 nm
      Reagent preparation• 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.
      Detailed protocol1. Grow cells in a tissue culture grade, flat-bottom plate in 100 µl of culture medium per well in a CO2 tissue culture incubator. For cell stimulation assays a starting concentration of 5,000-25,000 cells per well is recommended, for cytotoxicity assays the recommended number of cells per well is 25,000-150,000.
      2. After incubation add 10 µl of the WST-1 labeling mixture, prepared as above, to each well. Mix briefly by shaking gently for several min.
      3. Incubate adherent cells for 1-2 h and suspension cells for 3-4 h.
      4. Measure the absorbance of the samples using a microplate reader at a wavelength of 440-460 nm. If a reference wavelength is to be subtracted, a filter above 600 nm is recommended. The background absorbance is dependent upon the culture medium, pH, incubation time, and time of exposure to light. The typical background absorbance after a 2 h incubation is 0.1-0.2 absorbance units.

      HT-1080 cells incubated for 20 h followed by the addition of WST-1 labeling mixture. After additional 1 (Δ), 2.5 (⊄), and 4 h (•) incubations the absorbance was read at 450 nm.

      100,000 Jurkat cells per well were incubated overnight at 37°C in the presence of 0, 1, or 5 µg/ml camptothecin in RPMI medium containing 2% FBS. After the incubation 10 µl of the WST-1 labeling mixture was added and absorbance was read after a 2.5 h incubation at 37°C.
