Abstract

In this study, amodified xanthine oxidase activitymeasurementmethod is defined, and results obtained by the differentmethodswere compared. In the activitymeasurements, a commercialmilk xanthine oxidase enzyme productwas used as the sample. Significant differenceswere observed between the results of our modified method and those of original method (Method1).The resultsofourmodified method and othermethod (Method 2 inwhich no trichloroacetic acid is used) are however quite similar. Themodifiedmethod presented here eliminates faults of the previousmethods and gives comparable results.
