    Key Features

    • 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 separate measurement of NAD+ 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.

    Principals

    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 NAD+ is stabilized and measured.

    Reagents Provided   

    Extraction BUFFER A, NAD+ stabilizing reagent, NAD+ standard stock, Assay BUFFER C, Assay color reagent, Enzyme, Stop solution, Positive control

    Kit Requires 

    Multi-channel pipets. Two clear-bottom 96-well plates suitable for colorimetric assays, heat block with adjustable temperature (up to 80°C), spectrophotometric plate reader

    Precautions and Warnings

    For research use only by trained personnel.
    The Stop Solution may cause skin, eye, and respiratory irritation. Avoid breathing in fumes.
    Assay color reagent may cause skin irritation. Handle with care, use gloves.
    BUFFER A can cause eye irritation. Handle with care, use googles.
