| Description | NAD+ (β-Nicotinamide Adenine Dinucleotide) is a coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). |
| In vitro | METHODS: HEK293 cells were treated with FK866 (2 µM) and NAD+ (100 µM) for 48 h. Metabolic activity was determined by MTT Assay. RESULTS: Addition of FK866 to the culture medium resulted in rapid depletion of intracellular NAD stores and inhibition of the metabolic activity of NADPH-dependent dehydrogenase. When supplemented with additional NAD+, the metabolic activity of the cells returned to control levels. [1] METHODS: Isolated microvessels from rat retina were treated with NAD+ (0-1000 nM) for 0-24 h. Cell death was detected using trypan blue dye. RESULTS: Exposure to NAD+ increased microvascular cell death in a dose-dependent manner, with the half-maximum effective concentration of NAD+ being approximately 2 nM. assessment of the time course of NAD+-induced vascular toxicity showed that cell death was detected after 16 h of NAD+ exposure.

| In vivo | METHODS: To study the effects on ischemia/reperfusion (I/R) injury, NAD+ (5-20 mg/kg) was injected intravenously into Wistar rats with myocardial ischemia/reperfusion. RESULTS: Injections of 10-20 mg/kg NAD+ dose-dependently reduced I/R-induced myocardial infarction, with a dose of 20 mg/kg NAD+ reducing infarction by approximately 85%. Injection of NAD+ significantly reduced I/R-induced apoptotic cardiac injury. [3] |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
