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.

Application
60,000 Da未満のデキストランは、一般に低分子量デキストランとみなされます。低分子量デキストランは、高分子量デキストランと比べて、それらの粘度、凝集および透過特性のためにしばしば好まれます。高分子量の水溶性デキストランポリマーは、様々な生物医学的用途に使用されています。低分子量デキストランであるデキストラン（9,000～11,000）は、一過性の細胞膜および血液脳関門（BBB）の透過などのプロセスの研究に使用できます。それは、タンパク質のパッキングおよび折り畳みの研究における糖ベースのクラウディング剤として使用できます。[2]

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