L-谷氨酸/氨检测试剂盒[快速]

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

货号：K-GLNAM

规格：100 assays – 50 of each component

The L-Glutamine/Ammonia (Rapid) test kit is a novel method for the specific, convenient, cost effective and rapid measurement and analysis of L-glutamine and ammonia in culture media/supernatants and other materials.
Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC.

UV-method for the determination of L-Glutamine and Ammonia
in cell culture media, foodstuffs and other materials

Principle:
(glutaminase)
(1) L-Glutamine + H₂O → L-glutamate + NH₄⁺

(microbial glutamate dehydrogenase)
(2) NH₄⁺ + 2-Oxoglutarate + NADPH → L-glutamate + NADP⁺ + H₂O

Kit size:                            50 assays of each
Method:                            Spectrophotometric at 340 nm
Reaction time:                  ~ 15 min
Detection limit:                 0.54 mg/L (L-glutamine)
                                         0.06 mg/L (ammonia)
Application examples: 
Cell culture media and cultures, dietary supplements, vegetables
and other materials (e.g. biological samples, etc.)
Method recognition:          Novel method
