The material’s protein balance, pH, and ion content are constant across concentration levels. The kit material also contains multilevel assigned activities for alanine aminotransferase, alkaline phosphatase, alpha-amylase, aspartate aminotransferase, creatine phosphokinase, gamma-glutamyl transferase, lactate dehydrogenase, and lipase.
