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.

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.

Questions

1–9 of 9 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. Is Product D2534, cis-4,7,10,13,16,19-Docosahexaenoic acid soluble in DMSO? If so, what is the solubility of the product in DMSO?

    1 answer

    1. This product has not been tested for solubility in DMSO. However, various sources state this product can be solubilized in DMSO at a concentration of 100 mM.

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

    1 answer

    1. 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?

    1 answer

    1. 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.
