品牌：Megazyme

英文名：L-Arginine/Urea/Ammonia (Rapid) Assay Kit

货号：K-LARGE

规格：150 assays – 50 of each component

For the specific and rapid assay of L-arginine, urea and ammonia in grape juice/must and wine. Content:150 assays – 50 of each component

UV-method for the determination of L-Arginine, Urea and Ammonia 
in grape juice, must and wine

Principle:
                            (microbial glutamate dehydrogenase)
(1) 2-Oxoglutarate + NADPH + NH4+ → L-glutamic acid + NADP+ + 
                                                                                           H2O
                     (urease)
(2) Urea + H2O → 2 NH3 + CO2

                              (arginase)
(3) L-Arginine + H2O → urea + ornithine

Kit size:                              50 assays
Method:                              Spectrophotometric at 340 nm
Reaction time:                     ~ 20 min [ammonia (2 min), urea (6 min), 
                                           L-arginine (7 min)] Detection limit:                   0.07 mg/L (ammonia) 
                                           0.13 mg/L (urea) 
                                           0.37 mg/L (L-arginine)
Application examples: 
Grape juice, wine must, wine and other materials (e.g. biological 
cultures, samples, etc.)
Method recognition:            Improved method
