  • Method for measuring indoxyl sulfuric acid
    Patent number: 10150983
    Abstract: It is an object of this invention to provide a simple measurement method capable of detecting indoxyl sulfuric acid in a sample rapidly and at high sensitivity. By causing sulfatase and tetrazolium salt to act on indoxyl sulfuric acid in a sample to generate a formazan dye, and then calculating the generation amount of the formazan dye, indoxyl sulfuric acid in the sample can be measured more simply, more rapidly, and at higher sensitivity as compared with former methods.
