EnzyChrom™ Pyruvate Assay Kit


  • For quantitative determination of pyruvate and evaluation of drug effects on its metabolism.

Key Features

  • Sensitive and accurate. Use as little as 10 µL samples. Linear detection range in 96-well plate: 2 to 500 µM (17 µg/dL to 4.4 mg/dL) pyruvate for colorimetric assays and 0.2 to 50 µM for fluorimetric assays.
  • Simple and convenient. The procedure involves the addition of a single working reagent and incubation for 30 min at room temperature, compatible with HTS assays.
  • Improved reagent stability. The optimized formulation has greatly enhanced the reagent and signal stability.

More Details

Pyruvate is a key intermediate in cellular metabolic pathways. Pyruvate can be converted to carbohydrates via gluconeogenesis, to fatty acids or energy through acetyl-CoA, to the amino acid alanine, and to ethanol. Abnormal levels of pyruvate have been linked to liver diseases and metabolic disorders. Simple, direct, and automation-ready procedures for measuring pyruvate concentrations find wide applications in research and drug discovery. BioAssay Systems pyruvate assay uses a single Working Reagent that combines pyruvate oxidase and hydrogen peroxide determination in one step. The color intensity of the reaction product at 570nm or fluorescence intensity at λex/em = 530/585nm is directly proportional to pyruvate concentration in the sample.

I would like to use the EnzyChrom pyruvate assay kit (EYPR-100) to determine pyruvate levels in cell culture medium containing phenol red and fetal bovine serum. Does this interfere in any way with the measurement?

Phenol red adds a background to the OD measurement that will vary with the pH of the medium. Pyruvate in FBS will also add a background to the measurement. In order to correct for those interferences you should add a separate control with unused medium +FBS and subtract that from all sample values or, you could also prepare the standard in the medium + FBS. To play it safe. Alternatively you can use serum-free medium without phenol red.
