一般說明

葡聚糖（分子量410,000）属于中性多糖类家族，[1] 它是糖加工和其他食品生产行业中的污染物。这些糖由不同长度的α-(1-6) 糖苷键连接的D-葡萄糖单元所组成。[2]它们以细菌胞外多糖的形式存在于细菌中，据报道是由蔗糖通过有益乳酸菌（如肠膜明串珠菌和短乳杆菌）合成。它们可加入焙烤制品中以改善面包心质构、柔软度和面包体积，另外还可作为稳定剂和添加剂用于糖果、风味提取物、结冰组合物、饮料（包括软饮料、牛奶等）。[2]

應用


  • 药物递送中的葡聚糖：《Journal of Biomedical Materials Research Part A》的一项研究表明了生物聚合物葡聚糖如何促进伤口愈合。该研究重点关注了胶原蛋白-聚氨酯-葡聚糖水凝胶，这种水凝胶可以抑制炎症并促进胶原原纤维形成，这一性质使得葡聚糖对组织工程和医学应用至关重要（Aguayo-Morales et al., 2024）。

  • 作为血浆扩容剂的葡聚糖：《Redox Biology》的研究重点介绍了葡聚糖在减轻全身性铁过载应激中的作用。该研究提供了关于葡聚糖性质如何有利于贫血管理和其它血容量不足疾病的见解 (Zhao et al., 2024).

  • 细胞培养中的葡聚糖：《International Journal of Biological Macromolecules》上的一篇文章探讨了葡聚糖基抗菌水凝胶的应用。这些凝胶被用于生物分析应用中的荧光传感器，显示了葡聚糖在细胞培养和微生物监测中的用途（Bai et al., 2024）。

Dextran and Polysaccharides Overview

Dextrans are polysaccharides with molecular weights ≥1,000 Dalton, featuring a linear backbone of α-linked d-glucopyranosyl repeating units.

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/449/386/product-dating-information-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
