The L-Malic Acid test kit is suitable for the measurement and analysis of L-malic acid in grapes, grape juice and wine using the MegaQuant™ colorimeter (measurement at 505 nm). Suitable for white and red wines at all stages of the winemaking process.

 

Advantages

• Novel product, patented technology

• Highly stable reagents (at least three seasons use)

• Very competitive price (cost per test)

• Spectrophotometer / laboratory / expertise not required

• Very simple procedure

• Rapid reaction time (~ 6 min)

• Standard included

Principle:

(L-malate dehydrogenase)

(1) L-Malic acid + NAD+ ↔ oxaloacetate + NADH + H+

(glutamate-oxaloacetate transaminase)

(2) Oxaloacetate + L-glutamate → L-aspartate + 2-oxoglutarate

(diaphorase)

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

 

Kit size: 60 assays

Method: Spectrophotometric at 505 nm

Reaction time: ~ 6 min

Detection limit: 15.4 mg/L
