Principle:
(glutaminase)
(1) L-Glutamine + H2O → L-glutamate + NH4+
(microbial glutamate dehydrogenase)
(2) NH4+ + 2-oxoglutarate + NADPH → L-glutamate + NADP+ + H2O
(asparaginase)
(3) L-Asparagine + H2O → L-aspartate + NH4+
Kit size: 50 assays of each
Method: Spectrophotometric at 340 nm
Reaction time: ~ 20 min
Detection limit: 0.50 mg/L (L-asparagine) 0.54 mg/L (L-glutamine) 0.06 mg/L (ammonia)
