Cell Proliferation Kit (XTT based)

One step process, 1000 assays

SKU: 20-300-1000



Product Overview:

The Cell Proliferation Kit (XTT) was developed for cell proliferation assay in reaction to different growth factors, cytokines and nutrient components. In addition, it is suitable for assaying cytotoxicity of materials such as TNF or other growth inhibitors and for lymphocyte activation. Cell Proliferation Kit (XTT) is an excellent solution for the quantitating of cell proliferation and viability, without using radioactive isotopes. It can be used as a non-radioactive substitute for cytotoxic tests based on the release of 51Cr from cells, maintaining high sensitivity.


  • Easy to use, there is no need for additional reagents and/or cell washing procedures.
  • One Step Process, results within 2-5 hours.
  • Sensitivity, cell viability and proliferation can be assayed even in low cell concentrations.
  • Accuracy, dye absorbance is proportional to the number of cells in each well.
  • Safety, there is no need for radioactive isotopes.
  • Convenient, no instrumentation required except for a spectrophotometer (ELISA reader). The entire cell proliferation assay and cell viability assay can be performed directly in a microtiter plate.
