One unit (U) is defined as the quantity of enzyme required to liberate one μmol ammonia per minute at pH 7.3 and 37°C.
After reconstitution each ml contains 2,500 units of asparaginase.
* Produced in Escherichia coli cells by recombinant DNA technology.

Asparaginase hydrolyses asparagine to aspartic acid and ammonia. In contrast to normal cells, lymphoblastic tumour cells have a very limited capacity for synthesising asparagine because of a significantly reduced expression of asparagine synthetase. Therefore, they require asparagine which diffuses from the extracellular environment. As a result of asparaginase-induced asparagine depletion in serum, protein synthesis in lymphoblastic tumour cells is disturbed while sparing most normal cells.
Colourless 20 ml glass vial (Type I glass) closed with butylrubber stopper, aluminium seal and plastic flip-off cap, containing 10,000 units of asparaginase.
