上海金畔生物科技有限公司
品牌：Megazyme
英文名：Urea/Ammonia (Rapid) Assay Kit
货号：K-URAMR
规格：100 assays (50 of each) per kit
The Urea/Ammonia (Rapid) test kit is suitable for the specific and rapid measurement and analysis of urea and ammonia in water, beverages, milk and food products.
Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC.
UV-method for the determination of Urea and Ammonia in
foodstuffs, beverages and other materials
Principle:
(urease)
(1) Urea + H2O → 2NH3 + CO2
(microbial glutamate dehydrogenase)
(2) 2-Oxoglutarate + NADPH + NH4+ → L-glutamic acid + NADP+
+ H2O
Kit size: 50 assays of each
Method: Spectrophotometric at 340 nm
Reaction time: ~ 8 min
Detection limit: 0.13 mg/L (urea)
0.07 mg/L (ammonia)
Application examples:
Wine, grape juice, must, fruit juices, soft drinks, milk, cheese, meat,
processed meat, bakery products, seafood, fertilizers, feed,
pharmaceuticals, cosmetics, water (e.g. swimming-pool water), Kjeldahl
analysis, paper (and cardboard) and other materials (e.g. biological
cultures, samples, etc.)
Method recognition:
Methods based on this principle have been accepted by NEN and MEBAK
