Description

Docosahexaenoic Acid methyl ester is a methylated docosahexaenoic acid analog which can be intercalated into membrane phospholipids without being oxidized or hydrolyzed.

In Vitro

Sharp wave (SPW) incidence relative to baseline appears to decrease following Docosahexaenoic Acid methyl ester (DHA-Me) application[1]. There is no generation of a new protein band when bovine serum albumin (BSA) is exposed to the Fe2+ and ascorbic acid (AsA) mixed-function oxidation system in the absence of Docosahexaenoic Acid methyl ester (DHA). However, the high-molecular-weight protein band is observed after only 24 h when BSA is incubated with DHA. Incubation of BSA with 1.0 mM DHA leads to a substantial increase in protein carbonyl content and the addition of oxygen radical scavengers leads to a substantial decrease in protein carbonyl content[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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: ≥ 2.5 mg/mL (7.30 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (7.30 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 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 (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Kinase Assay
[2]

Protein (1 mg/mL) is incubated with Docosahexaenoic Acid methyl ester (DHA) (1.0 mM) in 50 mM HEPES buffer (pH 7.4) containing 0.2% (w/v) of Tween 20 at 37°C. Mannitol, histidine, sodium benzoate, or KI is added at final concentration of 0.5 M, 0.2 M, 0.5 M, or 0.1 M, respectively. Reactive oxygen species are generated by addition of FeSO4 (1 μM) and ascorbic acid (AsA, 20 μM)[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
