Application

cis-4,7,10,13,16,19-Docosahexaenoic acid has been used:
  • as a component in Dulbecco′s modified Eagle medium (DMEM) for culturing cells to perform docosahexaenoic acid (DHA) treatment
  • to study its impact on human induced pluripotent stem cell (iPSC)-derived neuronal at a molecular and cellular level
  • in MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay to study its cytotoxic effects on three human hepatocellular carcinoma (HCC) cell lines (HepG2, Hep3B, Huh7)

Biochem/physiol Actions

Docosahexaenoic acid (DHA) participates in the growth and physiology of the central nervous system. It regulates adult neurogenesis and neuroplasticity. DHA plays a key role in fetal brain development. It may exhibit antioxidant and anti-inflammatory properties. DHA plays a role in the regulation of cell membrane fluidity. It plays a vital role in several brain development processes, including neurotransmitter release, gene expression, myelination, neuroinflammation, and neuronal differentiation. DHA possesses an anticancer effect in several types of cancer.
Docosahexaenoic acid (DHA) serves as a precursor for signaling molecules such as prostaglandins and eicosanoids.

General description

Docosahexaenoic acid (DHA) is abundantly present in the brain.
Docosahexaenoic acid (DHA) is an omega-3 polyunsaturated fatty acid with 22 carbons and six double bonds, the first double bond occurring at position three from the methyl terminus (22:6 n-3). It is a component of lipid membranes and myelin sheath.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Is Product D2534, cis-4,7,10,13,16,19-Docosahexaenoic acid, a solution? If so, what is the solvent? If not, what is the density?

    D2534 is not a solution; it is a neat oil. The density of D2534 is approximately 0.95 g/mL.

  4. What is the best way to prepare a solution of Product D2534, cis-4,7,10,13,16,19-Docosahexaenoic acid?

    D2534 is soluble in chloroform at a concentration of 50 mg/mL. For biological or biochemical applications, chloroform is probably not suitable. Information in our files indicates that the product would be expected to be soluble in 95% ethanol to at least 10 mg/mL.

  5. After I prepare a solution of Product D2534, cis-4,7,10,13,16,19-Docosahexaenoic acid, in ethanol, how should it be stored?

    The solution in ethanol would be unstable.  It is best to make solutions up fresh.  If this is not possible, divide the solution into aliquots and layer argon or nitrogen over the solution in each vial.  Also, the product may be packaged in ampules, or kept in a vial with a cap plug or vacuum seal and stored at -70 °C.  Any antioxidant such as BHT (di-tert-butyl hydroxytoluene) will aid in preventing oxidation of this product.  BHT would be one of the better antioxidants to use.  It can be used at 0.1% w/w or in the most extreme cases up to 1%.  The most important thing to do to prevent oxidation is to exclude oxygen from contacting the product.

  6. I know that Product D2534, cis-4,7,10,13,16,19-Docosahexaenoic acid, is very prone to oxidation. I would like to study the oxidation in detail. Do you have any references?

    A rapid method for studying the oxidation of fatty acids, including linoleic acid, eicosapentaenoic acid and docosahexaenoic acid, has been published. Boyd, L.C., et al., A rapid method for determining the oxidation of n-3 fatty acids. J. Am. Oil Chem. Soc., 69, 325-330 (1992).

  7. Are all of the double bonds in the Product D2534, cis-4,7,10,13,16,19-Docosahexaenoic acid, in the cis-configuration?

    Yes, this product's double bond configuration is cis.

  8. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.
