    In Vitro

    Docosahexaenoic acid (DHA) is essential for the growth and functional development of the brain in infants. DHA is also required for maintenance of normal brain function in adults. The inclusion of plentiful DHA in the diet improves learning ability and memory[1]. DHA is an essential requirement in every step of brain development like neural cell proliferation, migration, differentiation, synaptogenesis. The multiple double bonds and unique structure allow DHA to impart special membrane characteristics for effective cell signaling. Many development disorders like dyslexia, autism spectrum disorder, attention deficit hyperactivity disorder, schizophrenia etc. are causally related to decreased level of DHA[2]. DHA is a potent RXR ligand inducing robust RXR activation already at low micro molar concentrations. The EC50 for RXRα activation by DHA is about 5-10 μM fatty acid[3].

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

    In Vivo

    Docosahexaenoic acid administration over 10 weeks significantly reduces the number of reference memory errors, without affecting the number of working memory errors, and significantly increases the docosahexaenoic acid content and the docosahexaenoic acid/arachidonic acid ratio in both the hippocampus and the cerebral cortex[4]. DHA treatment exerts neuroprotective actions on an experimental mouse model of PD. There is a decrease tendency in brain lipid oxidation of MPTP mice but it does not significantly[5].

    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% EtOH    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 5 mg/mL (15.22 mM); Clear solution

      This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (50.0 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% EtOH    90% (20% SBE-β-CD in Saline)

      Solubility: 5 mg/mL (15.22 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Animal Administration
    [4][5]

    Rats: Wistar rats are fed a fish oil-deficient diet through three generations. The young (five-week-old) male rats of the third generation are randomLy divided into two groups. Over 10 weeks, one group is perorally administered docosahexaenoic acid dissolved in 5% gum Arabic solution at 300 mg/kg/day; the other group receives a similar volume of vehicle alone. Five weeks after starting the administration, the rats are tested for learning ability related to two types of memory, reference memory and working memory, with the partially (four of eight) baited eight-arm radial maze[4].

    Mice: An experimental model of Parkinson's disease is created by four intraperitoneal injections of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (4×20 mg/kg, at 12 h intervals). Docosahexaenoic acid is given daily by gavage for 4 weeks (36 mg/kg/day). The motor activity of the mice is evaluated via the pole test. The activity of antioxidant enzymes in the brain are determined by spectrophotometric assays and the concentration of thiobarbituric acid-reactive substances (TBARS) are measured as an index of oxidative damage[5].

    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.
