General description

Dextran is an extracellular bacterial polymer of D-glucopyranose. It primarily consists of α-(1→6) linkage in the main chain and a variable amount of α-(1→2), α-(1→3), α-(1→4) branched linkages.

Application

Dextran from Leuconostoc spp. has been used:
  • for the isolation of islets from pancreatic tissue by centrifugation
  • as a component of Earle′s bicarbonate buffer for placental perfusion
  • for the isolation of rat brain microvessels

Biochem/physiol Actions

Dextran is a, which is commercially used as a drug, particularly as a blood plasma volume expander. It is used as an adjuvant, emulsifier, carrier, and stabilizer in the food, pharmaceutical, and chemical industries. Sephadex, a cross-linked dextran is broadly used for the separation and purification of protein. In the food industry, dextran found its use as a thickener for jam and ice cream. It inhibits the crystallization of sugar, thereby enhancing moisture retention. This helps in maintaining the flavor and appearance of various food items.

Questions

1–2 of 2 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
