Pyruvate Assay Kit Price
Product Description: Pyruvate is metabolized aerobically to acetyl-CoA and anaerobically to lactate (homolactic fermentation) or ethanol
(alcoholic fermentation in yeast). Pyruvate is also converted to oxaloacetate by an anaplerotic reaction mediated by pyruvate carboxylase, and
the oxaloacetate can be used for replenishing TCA cycle intermediates or promoting gluconeogenesis. Conversion of pyruvate to lactate is
obligatory for bacteria, serving to regenerate NAD+, and is enhanced in eukaryotic cells when mitochondrial function is impaired.
LDH-A-mediated conversion of pyruvate to lactate by cancer cells in the presence of adequate oxygen supply (aerobic glycolysis) constitutes
the central concept of the Warburg hypothesis, and is believed to be the underlying cause of tumorigenesis. The Pyruvate Assay Kit is based on
the difference in the UV absorption spectra between the oxidized and reduced forms of NAD+/NADH at 340 nm (detection sensitivity ~20 uM).
The assay requires a 0.1 ml Quartz cuvette for measuring kinetic changes in O.D.340 nm. Alternatively, a UV-transparent 96-well plate can be
used. The assay solution should be stored in aliquots at -80ºC, and will remain stable for several years at -80ºC.
