- Highly accurate and sensitive. Quantitation limit is 330 nM for NAD+ and 119 nM NADH in whole blood measured in two 96-well plate assays.
- Easy to handle. One step metabolite extraction is followed by separate measurement of NAD+ and NADH in the extract. Detection time is less than 10 minutes.
- High throughput. Can be easily adopted into high-throughput 96-well plate assay to analyze hundreds of samples per day.
Q-NADMED Blood, an in-vitro diagnostic medical device, is an analytical assay kit for measurement of concentrations of NAD+ and NADH metabolites in human whole blood. The assay is quantitative. Intended users of the Q-NADMED assay kit are trained laboratory personnel.
The principle of the assay is a cyclic enzymatic reaction with a colorimetric end-point detection. First, NAD+ and NADH metabolites are extracted together from a blood sample in a single step. Then the extract is divided into two parts revealing both NAD+ and NADH concentrations by removing one metabolite and stabilizing the other.
