{"product_id":"nad","title":"NAD+","description":"\u003cp\u003eNAD+ is a coenzyme involved in cellular redox chemistry and enzyme reactions. Its research value comes from two distinct roles: participating in electron transfer and serving as a substrate for enzymes that modify other molecules.\u003c\/p\u003e\u003ch2\u003eAbout NAD+\u003c\/h2\u003e\u003cp\u003eThe “+” identifies the oxidized form, which is paired with reduced NADH. Conversion between the two accompanies many metabolic reactions, so their relative amounts tell researchers something different from the total NAD pool. Studies using cellular biosensors examine that redox balance across metabolic conditions and within distinct cellular compartments.\u003c\/p\u003e\u003cp\u003eNAD+ also participates directly in protein-deacetylation reactions catalyzed by members of the sirtuin family. These enzymes remove acetyl groups from proteins. In this setting, NAD+ is consumed as part of the reaction instead of simply cycling between its oxidized and reduced forms.\u003c\/p\u003e\u003cp\u003eBecause NAD+ participates in both kinds of reaction, its availability sits at the intersection of metabolism and protein regulation. The balance between NAD+ and NADH describes redox state, while NAD-dependent enzyme activity reveals another aspect of how the coenzyme is being used.\u003c\/p\u003e\u003ch3\u003eResearch focus\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNAD+\/NADH balance in metabolic systems.\u003c\/li\u003e\n\u003cli\u003eNAD-dependent enzyme reactions.\u003c\/li\u003e\n\u003cli\u003eCellular and subcellular redox measurement.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality, Purity and Documentation\u003c\/h2\u003e\u003cp\u003eEvery lot of NAD+ is produced to a minimum purity specification of 99%, verified by high-performance liquid chromatography (HPLC) with mass spectrometry (MS) confirmation of molecular identity. A lot-specific Certificate of Analysis (COA) accompanies every batch and documents the analytical results for the exact material supplied, so laboratories can qualify the material against their own acceptance criteria before use.\u003c\/p\u003e\u003ch3\u003eAvailable sizes\u003c\/h3\u003e\u003cp\u003eNAD+ is supplied as a lyophilized (freeze-dried) powder in sealed vials in 500mg and 1000mg formats. Lyophilization removes water under vacuum at low temperature, producing a stable dry preparation suited to controlled laboratory storage and accurate gravimetric preparation of experimental solutions.\u003c\/p\u003e\u003ch3\u003eStorage and handling\u003c\/h3\u003e\u003cp\u003eStore lyophilized vials at -20°C or below, protected from light and moisture. Allow sealed vials to equilibrate to room temperature before opening to limit condensation inside the vial. Once opened, handle with clean laboratory technique, minimize exposure to ambient humidity, reseal promptly, and record the lot number in laboratory documentation for traceability.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eFor qualified in-vitro laboratory research only.
