- Certificate of Analysis is available upon request.
Please contact your NADMED representative or email us at info@nadmed.com. We will be happy to provide it.
- If you experience any issues, please refer to the troubleshooting guide.
Key Features
- Highly accurate and sensitive.
- Easy to handle. One step metabolite extraction is followed by separate measurement of NADP+ and NADPH 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.
Principles
The principle of the assay is a cyclic enzymatic reaction with a colorimetric end-point detection. First, NADP+ and NADPH metabolites are extracted together from a blood sample in a single step. Then the extract is divided into two parts revealing both NADP+ and NADPH concentrations by removing one metabolite and stabilizing the other.
