L-精氨酸/尿素/氨检测试剂盒[快速] L-Arginine/Urea/Ammonia (Rapid)

英文名:Integrated Total Dietary Fibre Assay Kit
规格:150 assays


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

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

(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.)
