SKU: 5WZZZZZ2045
$221.00

The L-Arginine/Urea/Ammonia test kit is specific and a rapid measurement and analysis of L-arginine, urea and ammonia in grape juice/must and wine.

 

Advantages

• Improved assay format

• Very rapid reactions due to use of uninhibited glutamate dehydrogenase

• All enzymes supplied as stabilised suspensions

• Very competitive price (cost per test)

• All reagents stable for > 2 years after preparation

• Mega-Calc™ software tool for hassle-free raw data processing

• Standard included • Extended cofactors stability

 

Principle:

(arginase)

(1) L-Arginine + H2O → urea + ornithine

(urease)

(2) Urea + H2O → 2 NH3 + CO2

(microbial glutamate dehydrogenase)

(3) 2-Oxoglutarate + NADPH + NH4+ → L-glutamic acid + NADP+ + H2O

 

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)
