NAD+ is nicotinamide adenine dinucleotide, a redox cofactor central to cellular metabolism and the substrate for the sirtuin and PARP enzyme families. It is used in hepatocyte, myotube and neuronal culture to study NAD/NADH ratio, sirtuin activity and DNA repair, and NuVion stocks it in Australia as a 500mg lyophilised vial.
- Nicotinamide adenine dinucleotide, a redox cofactor central to cell metabolism
- Substrate for the sirtuin and PARP enzyme families
- Applied in NAD/NADH ratio, sirtuin activity and DNA repair assays
- Supplied lyophilised, purity by RP-HPLC and identity by mass spectrometry
NAD+ structure and research use
NAD+ is built from two nucleotides, one carrying nicotinamide and one carrying adenine, joined through their phosphate groups. It cycles between an oxidised form, NAD+, and a reduced form, NADH, as it carries electrons between metabolic reactions, and it is consumed as a substrate by sirtuins and PARPs. In the laboratory it is used in hepatocyte, myotube and neuronal models for work on redox balance, sirtuin activity and DNA repair signalling.
NAD+ research applications
- Coupled spectrophotometric assays following absorbance at 340 nm to measure dehydrogenase kinetics and Km
- Sirtuin deacylase activity assays with fluorogenic peptide substrates and nicotinamide product inhibition studies
- PARP activity assays and characterisation of ADP-ribosylated proteins in cell lysates
- Calibration curve and retention time reference for ion-pairing HPLC or LC-MS/MS quantification of coenzyme pools
