NAD+

NAD+ is a Nicotinamide Adenine Dinucleotide supplied for laboratory research. Essential cellular coenzyme studied in vitro for ATP synthesis pathway modeling, DNA repair mechanism analysis, sirtuin activation research, and cellular-aging pathway signaling.

NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme central to cellular energy (ATP) production, and it is studied as a substrate for sirtuins and PARP enzymes in DNA-repair and cellular-aging research pathways.

NAD+ is supplied as a lyophilized (freeze-dried) powder — a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently — never shaken — until the powder fully dissolves. All handling is for in vitro research use only.

Store the lyophilized NAD+ powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.

Every batch of NAD+ is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods — high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
