Key Features

 

  • Highly accurate and sensitive.
  • Easy to handle. One step metabolite extraction is followed by separate measurement of NAPD+ 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.

Principals

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 tissue or cell culture 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.

Reagents Provided   

Extraction BUFFER A, NAPD+ stabilizing reagent, NADPH stabilizing reagent, NADP+ standard stock, NADPH 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

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.
