In Vitro

Vitamin E is a lipid-soluble, chain-breaking type of antioxidant present in human blood. Vitamin E works as a free radical scavenger and has the primary function of destroying peroxyl radicals. Thus, it protects long-chain polyunsaturated fatty acids (e.g., cell membranes or low-density lipoprotein cholesterol) from oxidation or destruction. Its association with vitamin C is of great pathophysiological importance, because inhibition of lipid peroxidation by α-tocopherol occurs through its conversion into an oxidized α-tocopheroxyl radical, which in turn is regenerated to α-tocopherol through reduction by redox-active reagents^[1].
α-Tocopherol can inhibit the recruitment of lymphocytes and eosinophils^[1].

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

In Vivo

In order to longitudinally relate vitamin E status, evaluated by means of α- and γ-tocopherol measured in erythrocytes membranes, to inflammatory state and oxidative stress by means of total antioxidant capacity of plasma and lipid peroxidation biomarkers, and to assess its association to hard long-term outcomes (e.g., overall and cause-specific graft and recipient loss), and to be able to likewise account for liver, lung, and heart transplant recipients^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 1.61 mg/mL (3.74 mM); Clear solution

This protocol yields a clear solution of ≥ 1.61 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.1 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 1.61 mg/mL (3.74 mM); Clear solution

This protocol yields a clear solution of ≥ 1.61 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.1 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
