Product overview
Pyruvate dehydrogenase (PDH) Enzyme Activity Microplate Assay Kit (ab109902) can be used to determine the activity of PDH in a human, bovine, mouse, or rat sample. The PDH enzyme is immunocaptured within the wells of the microplate and activity is determined by following the reduction of NAD+ to NADH, coupled to the reduction of a reporter dye to yield a colored reaction product with an increase in absorbance at 450 nm at room temperature. Included for performance of the activity assay are buffer, detergent, reagent mix, and a 96-well microplate with monoclonal antibody pre-bound to the wells of the plate, allowing for a stream-lined assay.
This assay is optimized for use with whole tissue extract when the amount of total material available for assay is 20-100 µg or more. If using cell extract of cultured cells 1 mg of material is required due to the very low levels of enzyme and reduced levels of mitochondria in the extract.
The PDH complex is relatively fragile and sensitive to detergent. Please follow the sample preparation steps provided in the protocol booklet. Other preparation methods may decrease PDH activity. Our Scientific Support team is happy to answer any questions about sample prep.

Functional Studies - Pyruvate dehydrogenase (PDH) Enzyme Activity Microplate Assay Kit (ab109902)Mitochondria, tissue extracts and whole cultured cell extracts all show linear relationships between signal and sample load at limiting concentrations. The rates shown were determined as change in OD over time, and these are best represented as change in milliOD per minute.
