General description

Dimethylsulfoxid (DMSO) ist ein wirksames aprotisches Lösungsmittel. Es ist farblos, geruchlos und von Natur aus hygroskopisch. DMSO verbessert die Permeabilität von verschiedenen hydrophilen und lipophilen Permeationsmitteln. Es ist eines der im Labor am häufigsten eingesetzten Lösungsmittel.

Application

Dimethylsulfoxid (DMSO) wird in verschiedenen experimentellen Untersuchungen als Träger für Testverbindungen eingesetzt.[1] Es wird auch als Lösungsmittel im Amyloid β (Aβ)-Aggregationsprotokoll zur erneuten Solubilisierung von Peptid eingesetzt, um seinen dissoziierten Zustand zu erhalten.

Other Notes

Polybren/DMSO-unterstützter Gentransfer[2]

Disclaimer

Unterkühlt leicht und schmilzt langsam bei Raumtemperatur. Das verfestigte Produkt kann durch Erwärmen auf Raumtemperatur wieder verflüssigt werden, ohne dabei geschädigt zu werden.

Questions

1–10 of 11 Questions  
  1. 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/418/501/product-dating-information-06-25-mk.pdf

  2. 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

  3. Dimethyl sulfoxide (DMSO) should be a liquid.  Why did it arrive as a solid?

    1 answer
    1. DMSO supercools easily, and re-melts slowly at room temperature. The melting point is 16-19 °C. The solidified product can be re-liquefied by warming to room temperature without detriment to the product.
