一般描述

本品按现行药典规定交付。所有为支持本产品而提供的信息,包括SDS和任何产品信息单均由药典颁发机构制定并发布。如需进一步信息和支持,请访问现行药典网站。

应用

Glutamine USP reference standard, intended for use in specified quality tests and assays as specified in the USP compendia. Also, for use with USP monographs such as:
  • Glycyl-l-glutamine
  • l-Alanyl-l-glutamine

生化/生理作用

L-谷氨酰胺是一种必需氨基酸,作为细胞培养过程中主要的能量来源而成为培养基的重要组分。L-谷氨酰胺在干粉及冷冻溶液的状态下极为稳定。然而,L-谷氨酰胺在液体培养基或储存溶液中均会相对较快的降解。最佳的细胞表现通常需要在使用前向培养基中添加L-谷氨酰胺补充剂。

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.

  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
