Application

Dextran sulfate sodium salt from Leuconostoc sp. is a polyanion used as a test reagent for testing its capability to rupture the extracellular enveloped virus (EEV) outer membrane.[1] It has also been used for assessing the impact of TLR4 monoclonal antibody on the growth of dextran-sulfate-sodium-(DSS)-induced colitis.[2]

Actions biochimiques/physiologiques

Dextran is a mixture of glucose polymers of varying size and geometry.Dextran in the form of dextran sulphate sodium acts as an anticoagulant. Dextran interferes with blood clot formation by acting on blood coagulation factors and the function of platelets. It prolongs the time required for formation of the clot and decreases the maximum clot strength.[3][4] The disturbance of homeostasis by dextran may cause increased bleeding, colitis and kidney failure.[5][6]

Questions

1–5 of 5 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
