Allgemeine Beschreibung

Dextran ist ein Polymer von Anhydroglucose. Es besteht aus ca. 95 % alpha-D-(166)-Verbindungen. Die restlichen (163) Verbindungen tragen zur Verzweigung des Dextrans bei.

Anwendung

Dextransulfat wird regelmäßig verwendet für die selektive Fällung von Lipoproteinen, Sondenhybridisierung membranimmobilisierter DNA, Freisetzung von DNA aus DNA-Histonkomplexen und Hemmung der RNA-Bindung an Ribosomen.

Biochem./physiol. Wirkung

Die Behandlung mit Dextransulfat-Natrium löst bei Mäusen und Ratten die Entstehung von Colitis aus, indem es im Kolon an Fettsäuren mittlerer Kettenlänge bindet und eine Entzündung induziert. [1]

Questions

1–4 of 4 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.

  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. Does DDS (Dextran Sodium Sulfate) come in a USP grade for a animal studies?

    1 answer

    1. Unfortunately, there is no pharmaceutical grade Dextran Sodium Sulfate available at this time. This product is not tested for use in animal models. It would be up to the researcher to determine suitability.

  4. Hello! I want to know if you can autoclave water with 4% of dextran sulfate sodium (DSS) without decomposing the DSS.

    1 answer

    1. The solubility of dextran sulfates is tested at 100 mg/mL in water. Clear solutions are obtained. Buffered aqueous dextran sulfate solutions can be sterilized by autoclaving at 110-115 °C for 30 to 45 minutes. Dextran can be hydrolyzed by strong acids at high temperatures. Dextran sulfate has a higher affinity for calcium ions than for sodium ions. The calcium salt of dextran sulfate is insoluble. The free acid (hydrogen) form of dextran sulfate is extremely acidic and autohydrolyzes rapidly in solution and as a powder.
