In Vitro

α-Vitamin E ((+)-α-Tocopherol) is a peroxyl radical scavenger. The importance of this function is to maintain the integrity of long-chain polyunsaturated fatty acids in the membranes of cells and thus maintain their bioactivity^[1].
α-Vitamin E ((+)-α-Tocopherol) has been described to inhibit PKC in various cell types with consequent inhibition of platelet aggregation, endothelial cell nitric oxide production and superoxide production in neutrophils and macrophages. α-Vitamin E ((+)-α-Tocopherol) exposure induced the activation of both the MAP kinase and PI3 kinase (PI3K) pathways, suggesting that it is the oxidative stress that up-regulates kinase pathways and the antioxidant action of α-tocopherol protects the cell membrane fatty acids^[1].
α-Vitamin E ((+)-α-Tocopherol) has proposed benefits for influenza virus A infection, as well as possible activity against hepatitis B and C. α-Vitamin E shows proviral effects, particularly in HEK293T/17 cells^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

α-Vitamin E ((+)-α-Tocopherol) prevents the increase in the pro-inflammatory cytokines IL-1, IL-6, and IFN-γ mRNA and protein compared with the ischemic-reperfused myocardium from untreated pigs and compared to the non-injured area^[1].
α-Vitamin E (D-α-Tocopherol; intraperitoneal injection or oral administration) treatment induces an amelioration of diabetic nephropathy in mice through the activation of diacylglycerol kinase α (DGKα) and the prevention of podocyte loss^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
