D- / L-乳酸(D- / L-乳酸)(快速)测试试剂盒用于快速,特异的同时测量和分析L-乳酸(L-乳酸)和D-乳酸(D-乳酸) 乳酸盐)在饮料,肉类,乳制品和食品中的应用。
UV-method for the determination of D-/L-Lactic Acid in
foodstuffs, beverages and other materials
Principle:
(D-lactate dehydrogenase)
(1) D-Lactic acid + NAD+ ↔ pyruvate + NADH + H+
(glutamate-pyruvate transaminase)
(2) Pyruvate + D-glutamate → D-alanine + 2-oxoglutarate
(L-lactate dehydrogenase)
(3) L-Lactic acid + NAD+ → pyruvate + NADH + H+
Kit size: * 50 assays of each
* The number of manual tests per kit can be doubled if all volumes are halved.
This can be readily accommodated using the MegaQuantTM Wave
Spectrophotometer (D-MQWAVE).Method: Spectrophotometric at 340 nm
Reaction time: ~ 10 min (L-lactic acid) and ~ 5 min (D-lactic acid)
Detection limit: 0.21 mg/L
Application examples:
Wine, soft drinks, milk, dairy products, foods containing milk (e.g. dietetic
foods, bakery products, baby food, chocolate, sweets and ice-cream),
vinegar, fruit and vegetables, processed fruit and vegetables, meat
products, food additives, paper (and cardboard), cosmetics, pharmaceuticals
and other materials (e.g. biological cultures, samples, etc.)
Method recognition:
Methods based on this principle have been accepted by DIN, GOST,
IDF, EEC, EN, ISO, OIV, IFU, AIJN and MEBAKAdvantages
- Rapid total analysis time (concurrent / flexible D and L-lactic acid reaction format)
- D-lactate dehydrogenase reaction very rapid with most samples (~ 5 min)
- Very competitive price (cost per test)
- All reagents stable for > 2 years after preparation
- Mega-Calc™ software tool is available from our website for hassle-free raw data processing
- Standard included
- Extended cofactors stability
