CheKine™ Micro Soil-Fluorescein Diacetate (S-FDA) Hydrolase - 48 T/48 S

The hydrolysis reaction of FDA can well reflect the changes of microbial activity and soil quality in soil and the transformation of organic matter in ecosystem, which is one of the important biological indexes in soil quality research. CheKine™ Micro Soil Fluorescein Diacetate (S-FDA) Activity Assay Kit can detect biological samples such as soli. In this kit, FDA is a colorless compound, which can be hydrolyzed by many soil enzymes in the medium, and after dehydration reaction, fluorescein, the final product of enzymatic hydrolysis, is stable and difficult to decompose, and has a strong absorption peak at 490 nm. The activity of S-FDA hydrolase can be calculated by detecting the change of absorption value at 490 nm.
