應用

来自长角豆（Ceratonia siliqua ）种子的角豆胶（LBG，半乳甘露聚糖多糖）可作为底物，以帮助鉴定、区分和表征甘露聚糖酶，如 β-甘露聚糖酶（EC 3.2.1.78）。 LBG可用于开发药物递送设备。 通过球磨破坏桉树和微晶纤维素的结晶度时，可使用LBG研究其作为保护剂的性质。 LBG可用于研究其作为食品添加剂的性质，它能减少由黄曲霉引起的腐败。LBG可以用作超支化N-聚糖核心结构的有机合成的起始材料。

其他說明

它被认为是甘露糖的直链聚合物，每四个甘露糖上有一个半乳糖分支，分子量约为310 kDa。

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
