DNAse Test Agar

DNase Test Agar is used to detect deoxyribonuclease activity of bacteria and fungi, particularly for the identification of Staphylococci. Casein Enzymatic Hydrolysate and Papaic Digest of Soybean provide nitrogenous sources, carbohydrates, minerals, and trace elements. DNA allows for the measurement of DNase activity upon addition of Toluidine Blue or Methyl Green. Sodium Chloride maintains the osmotic balance and Agar is the gelifying agent.
