EnzyChrom™ Pyruvate Assay Kit
Datasheet PDF  MSDS/Bulk Order

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 addition of a single working reagent and incubation for 30 min at room temperature, compatible for HTS assays.

Improved reagent stability. The optimized formulation has greatly enhanced the reagent and signal stability.

OD570nm, or FL530/585nm



20 min

100 tests

Detection Limit
OD, FL: 2, 0.2 μM

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.

1. 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.
