The D-Isocitric Acid test kit is for the specific and rapid measurement and analysis of D-isocitric acid in fruit juices.
Suitable for manual, auto-analyser and microplate formats.

UV-method for the determination of D-Isocitric Acid in foodstuffs

Principle:
(isocitrate dehydrogenase)
(1) D-Isocitric acid + NADP⁺ → 2-oxoglutarate + CO₂ + NADPH + H⁺

(pH 9-10)
(2) D-Isocitric acid ester + H₂O → D-isocitric acid + alcohol

(pH 9-10)
(3) D-Isocitric acid lactone + H₂O → D-isocitric acid

Kit size:                           100 assays (manual) / 1000 (microplate) 
                                         / 1000 (auto-analyser)
Method:                            Spectrophotometric at 340 nm
Reaction time:                  ~ 3 min
Detection limit:                 0.35 mg/L
Application examples: 
Fruit juices, fruit products, soft drinks and other materials (e.g. biological
cultures, samples, etc.) 
Method recognition:     
Methods based on this principle have been accepted by EN, NEN, NF,
DIN, GOST, IFU and AIJN
