- Highly accurate and sensitive. Quantitation limit is 330 nM for NAD+ in whole blood measured in two 96-well plate assays.
- Easy to handle. One-step metabolite extraction is followed by measurement of NAD+ in the extract. Detection time is less than 10 minutes.
- 40 samples can be measured at once or two separate times e.g. 20+20
- 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+ metabolite 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+ is extracted from a blood sample in a single step. After this, the NAD+ is stabilized and measured.
