| Description | 4-Hydroxynonenal (4-HNE) (4-HNE) is an oxidative/nitrosative stress biomarker. It is a substrate and an inhibitor of acetaldehyde dehydrogenase 2 (ALDH2). |
| In vitro | 4-Hydroxynonenal (4-HNE) is both a substrate and an inhibitor of ALDH2, with inhibition reversible at low concentrations and becoming irreversible at 10 μM. It induces antioxidant defense mechanisms to limit its own production and enhance cellular protection against oxidative stress. As a product of lipid peroxidation, 4-HNE is mutagenic and genotoxic in viruses, bacteria, and mammalian cells, reacting with all four DNA bases with varying efficiency (G > C > A > T). 4-Hydroxynonenal-dG serves as the best biomarker of its genotoxic effects, primarily found in nuclear DNA [1]. |
| In vivo | Twenty-four hours after fluid percussion injury (FPI), mouse brain tissue is analyzed for the expression levels of NADPH oxidase 1 (NOX1), inducible nitric oxide synthase (iNOS), and 4-Hydroxynonenal (4-HNE). Both wild-type (Nrf2+/+) and Nrf2-deficient (Nrf2-/-) mice show increased 4-HNE expression following a moderate 15 psi injury compared to uninjured controls. In Nrf2-/-knockout mice, 4-HNE expression is significantly higher than in corresponding injured and uninjured Nrf2-/-wild-type animals [2]. |

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.
