About us

Dojindo has developed the WST method

WST (water-soluble Tetrazolium) was developed by the DOJINDO Laboratories in 1990s and is now used worldwide as one of the methods for cell proliferation assay. The CCK (Cell Counting Kit) and the CCK-8 (Cell Counting Kit-8) with improved sensitivity, which were commercialized using the WST method, are original products for which more than 5,000 papers have been published worldwide.


About Dojindo Laboratories

Dojindo Laboratories was founded by Dr. Keihei Ueno, a well-known researcher in chelating chemistry.
