The L-Glutamic Acid test kit is a simple, reliable, rapid and accurate method for the measurement and analysis of L-glutamate (MSG) in foodstuffs.
Suitable for manual, auto-analyser and microplate formats.

Colourimetric method for the determination of L-Glutamic Acid
(Monosodium Glutamate; MSG) in foodstuffs and other materials

(beef liver glutamate dehydrogenase)
(1) L-Glutamic acid + NAD+ + H2O ↔ 2-oxoglutarate + NADH + NH4+

(2) INT + NADH + H+ → NAD+ + INT-formazan

Kit size: 60 assays (manual) / 600 (microplate)
/ 700 (auto-analyser)
Method: Spectrophotometric at 492 nm
Reaction time: ~ 9 min
