Available Options

* CCK-8 Kit Size:






Cell Counting Kit-8 (CCK-8) allows sensitive colorimetric assays for the determination of cell viability in cell proliferation and cytotoxicity assays. 

  • Simple to use
  • Non-radioactive colorimetric assay 
  • Out-performs old generation assays (e.g. MTT, MTS or XTT)

How it works

Dojindo’s highly water-soluble tetrazolium salt, WST-8, is reduced by dehydrogenase activities in cells to give a yellow-color formazan dye, which is soluble in the tissue culture media. The amount of the formazan dye, generated by the activities of dehydrogenases in cells, is directly proportional to the number of living cells. The detection sensitivity of CCK-8 is higher than the other tetrazolium salts such as MTT, XTT, MTS or WST-1.


Applications:

Non-Radioactive Cell Proliferation or Cytotoxicity Assay

The Cell Counting Kit-8 (CCK8) is a one-bottle kit that requires no premixing.  This non-radioactive, sensitive colorimetric assay allows accurate live cell counting in a cell proliferation or cytotoxicity assay applications.  CCK8 based assay has excellent correlation with results of traditional radioactive [3H]-thymidine incorporation assay.

Other Applicable Assays:

  • Cell viability.
  • Chemosensitivity.
  • Cell attachment determination.
  • Chemotaxis

CCK-8 Out Performs Old Generation Colorimetric Cell Proliferation Compounds: MTT, MTS and XTT

CCK-8 has significantly higher signal


CCK-8 is less toxic to cells than WST-1or MTS:


CCK-8 is easier to use: Just add CCK-8 and measure!


Available Kit Sizes:

CCK-8 Kits are available in the following sizes: 100 tests, 500 tests, 1000 tests, 3000 tests and 10000 tests

 

Cell Counting Kit-8 Frequently Asked Questions

  1. How many cells should there be in a well?

For adhesive cells, at least 1000 cells are necessary per well (100 μl medium) when using the kit's standard 96-well plate. For leukocytes, at least 2500 cells are necessary per well (100 μl medium) because of low sensitivity. The recommended maximum number of cells per well for the 96-well plate is 25000. If a 24-well or 6-well plate is used for this assay, please calculate the number of cells per well accordingly, and adjust the volume of the CCK-8 solution in a well to 10% of the total volume.

  1. Does CCK-8 stain viable cells?

No, it does not stain viable cells because the water-soluble tetrazolium salt  is used in the CCK-8 solution. The electron mediator, 1-Methoxy PMS, receives electrons from a viable cell and transfers the electron to CCK-8 in the culture medium. Since its formazan dye is also highly water-soluble, CCK-8 cannot be utilized for cell staining purpose.

  1. How stable is CCK-8?

CCK-8 is stable for 2 years at -20 ℃, 1 year at 4 ℃, and 6 months at room temperature. CCK-8 is stable over 2 days even at 60℃ as long as the CCK-8 solution keeps its original red color and does not turn orange.

  1. Does phenol red affect the assay?

No. The absorption value of phenol red in a culture medium can be removed by subtracting the absorption value of a blank solution from the absorption value of each well. Therefore, a phenol red containing mediums’ usable for the CCK-8 assay.

  1. Is there a correlation between CCK-8 and the Thymidine incorporation assay?

Yes. For correlation graphs, see page 1. Please note that since CCK-8 uses a different assaying mechanism from that of the Thymidine assay, the CCK-8 and Thymidine assay results may differ.

  1. Is CCK-8 toxic to cells?

The toxicity of CCK-8 is so low that, after the CCK-8 assay is completed, the same cells can be used for other cell proliferation assays such as the crystal violet assay, neutral red assay or DNA fluorometric assay

  1. I do not have a 450 nm filter. What other filters can I use?

You can use filters with the absorbance between 450 and 490 nm, even though 450 nm filter gives the best sensitivity.
