INTRODUCTION:

The most widely used method for enzymatic quantification of acetic acidis that based on the use of acetyl-coenzyme A synthetase (ACS),according to equations 1 – 3 below. For auto-analyser applications itbecomes necessary to prepare a “master mix” reagent (R1), containing allcomponents of the assay except the reaction initiation enzyme, ACS.However, reagent R1 when prepared from some kits has very limitedon-machine stability, owing to a rapidly increasing absorbance value. Toovercome this issue, Megazyme developed this kit (K-ACETAF), thatdoesn’t exhibit this instability phenomenon. Additionally, theanti-inhibitory compound polyvinylpyrollidone (PVP) has also beenincorporated into the assay to prevent inhibition caused by certaintannins found in grape juice and wine.

KITS:

Kits suitable for the preparation of 141.6 mL of reagent (equivalent to456 reactions of 0.31 mL) are available from Megazyme.

The kits contain the full assay method plus:

Bottle 1: Buffer (30 mL, pH 8.4) plus L-malic acid, PVP and sodiumazide (0.02 % w/v) as a preservative. Stable for > 2 years at 4°C.

Bottle 2: (x2) NAD+ plus ATP and CoA.Freeze dried powder.Stable for> 5 years at -20°C.

Bottle 3: L-Malate dehydrogenase plus citrate synthase suspension, 2.2mL. Stable for > 2 years at 4°C.

Bottle 4: Acetyl-coenzyme A synthetase suspension (1.1 mL). Stable for> 2 years at 4°C.

REAGENT PREPARATION:
