Product description
Asparaginase (ASNase, EC 3.5.1.1) is a type of amide enzyme that catalyzes the hydrolysis of asparagine into aspartic acid and ammonia, playing an important regulatory role in nitrogen metabolism. Soil asparaginase (S-ASNase) catalyzes the hydrolysis of asparagine into aspartic acid and ammonia. Ammonia, in a strong alkaline environment, reacts with hypochlorite and phenol to form the water-soluble dye indigo blue, which has a stable solution color. It has a characteristic absorption peak at 630nm, and by detecting the rate of increase of ammonia, the enzyme activity can be calculated.
