一般描述

甘油是一种无味、无色、粘性的，并且具有甜味的液体。它可以是天然来源，也可以来自石化原料。甘油具有广泛的应用，是自然界中最有价值和多功能的化学物质之一。它可可用作润肤剂、溶剂、甜味剂，用于药物配方、化妆品、食品和洗漱用品中。它非常稳定，可以在常温下储存；它也没有刺激性，对环境没有不良影响。

应用

甘油溶液已被用于：
  • 制备血液模拟液[1]
  • 表皮模仿膜[2]
  • 作为核储存缓冲液的组成部分[3]

生化/生理作用

甘油已被用作
  • 结核分枝杆菌 和 鸟分枝杆菌 细胞培养过程中的补充剂。
  • 在设计酶生物燃料电池期间的燃料。
  • 含有4-HCCA和3-氨基喹啉的液体复合基质，以用于对中性和酸性聚糖进行分析。
  • 快速原子轰击MS的基质。
  • 通过MALDI（基质辅助激光解吸/电离质谱）分析进行定量研究的液体基质。
甘油本质上是吸湿的，并且由于其三个亲水性醇羟基而可溶于水。它可以形成分子间和分子内氢键，使其成为一种非常灵活的分子。甘油的生理作用包括细胞介导的免疫、增加IgG的产生、以及增加组胺的释放。

其他说明

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

    Glycerol for cover slipping

    I mainly bought this product to temporarily cover slip slides for imaging purposes before continuing with my experiments. There was no need to dilute the glycerol when cover slipping and it was easy to remove the cover once the imaging was done.
