CoA on release

NAD+ is the oxidised form of nicotinamide adenine dinucleotide, a ubiquitous coenzyme in redox biochemistry. Laboratories use high-purity NAD+ to study sirtuin activity, PARP-dependent DNA repair readouts, mitochondrial respiration assays, and NAD salvage-pathway pharmacology — research use only.

What is NAD+?

Nicotinamide adenine dinucleotide (NAD⁺) is a dinucleotide coenzyme composed of two nucleotides joined through their phosphate groups. In its oxidised form it accepts hydride equivalents during catabolic metabolism and serves as an essential electron carrier linking glycolysis, the TCA cycle, and oxidative phosphorylation.

Beyond classical bioenergetics, NAD⁺ is a substrate for enzymes including sirtuins (SIRT1–7), poly(ADP-ribose) polymerases (PARPs), and CD38/BST1 ectoenzymes that regulate DNA repair, chromatin remodelling, and immune-cell metabolism.

Optimus Peptides supplies lyophilised NAD⁺ exclusively for lawful laboratory research — not for human or veterinary use, and not as a dietary supplement.

Presentation

500mg lyophilised vial

Research Background

NAD⁺ biology spans enzymology and systems-level metabolism research. Common themes include:

Quantifying NAD⁺/NADH ratios in cells and organoids using enzymatic cycling or LC-MS.
Probing sirtuin activity after controlled NAD⁺ repletion or depletion.
PARP activation models where NAD⁺ consumption links genotoxic stress to energetic collapse.
Mitochondrial stress tests where extracellular NAD⁺ modulates respiration readouts.
Comparative studies with NAD⁺ precursors (NMN, NR) versus direct coenzyme delivery.

Research Applications

Cell-culture supplementation for redox and ageing pathway screens
Enzyme kinetic assays requiring defined cofactor concentrations
Pairing with mitochondrial-derived peptides such as MOTS-c in metabolic models

Frequently Asked Questions

How is NAD+ different from NMN or NR?

NMN and NR are precursors converted through the salvage pathway. This product is the coenzyme itself for direct addition protocols.

Is NAD+ the same as retail “NAD boosters”?

No. Our material is sold strictly for qualified laboratory research.
