Keston5 modified this method in the early 1950's using glucose oxidase/peroxidase enzyme system and o-dianisidine chromogen systems. 2N Sodium hydroxide (NaOH) 8g of NaOH is dissolve and finally make up the volume to 100ml with distilled water. This volume incorporates analytical fluorescence-based glucose sensing reviews, specialized enough to be attractive to professional researchers, yet appealing to a wider audience of scientists in related disciplines of fluorescence. Linearity and precision NelsonSomogyi Method 2. Found inside Page 111Take three cleaned test tubes and label them as S (standard), B (blank), and T (test). 3. Add the reagents as shown in the table: Summary 1. The glucose oxidase (GOD-POD) method is an easy and accurate method of glucose estimation. 2.
