Dische test
Chemical test
From Wikipedia, the free encyclopedia
The Dische test, or Dische reaction, is used to distinguish DNA from RNA. It was invented by Zacharias Dische.
Method
Dische's diphenylamine reagent consists of diphenylamine, glacial acetic acid, sulfuric acid, and ethanol.[1]
When heated with DNA, it turns blue in the presence of DNA. A more intense blue color indicates a greater concentration of DNA.
