应用

L-谷氨酰胺是一种必需氨基酸,是培养基的重要组成部分,是培养细胞的主要能量来源。细胞的最佳性能通常需要在使用前在培养基中添加L-谷氨酰胺。

生化/生理作用

L-谷氨酰胺是一种基本氨基酸,是作为细胞培养主要能源的培养基所必不可少的组成部分。L-谷氨酰胺干粉和冷冻溶液十分稳定。但液体培养基或储存液中的 L-谷氨酰胺分解相对较快。使用前,通常需要补充含 L-谷氨酰胺的培养基,以获得最佳细胞性能。

制备说明

用细胞培养级超纯水制备。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. Is the molecular weight of L-Glutamine 146.14 or 146.15? The label information changed.

    Based on a molecular formula of C5H10N2O3, the molecular weight to seven significant figures is 146.1456. Over the years, this value may have been reported in Sigma-Aldrich documentation or on labels as either 146.15 (by rounding up) or 146.14 (by truncation). The material itself has not changed.

  6. Why is there a precipitate in the 200 mM L-glutamine solution, products G7513 and G2150, after thawing at room temperature?

    L-Glutamine, 200 mM solution, tends to precipitate in solution when chilled.  After thawing, it will be an opalescent solution.  If allowed to settle, there can be some crystalline insolubles at the bottom of the bottle.The product should be warmed to 37°C for complete solubilization.  To limit the number of times the product needs to be warmed to 37°C, the product can be divided into working aliquots which are stored at -20°C and used as needed.  This will expose the product to the minimal amount of warming cycles.  

  7. My question is not addressed here, how can I contact Technical Service for assistance?

Human Renal Proximal Tubule Epithelial Cells (RPTEC) as an Essential Advanced Model to Express Kidney Drug Transporters and Toxicity

Human renal proximal tubule epithelial cells (RPTECs) are commonly used to predict human renal drug permeability and to investigate drug efflux. We have generated transporter knockout (KO) cell lines using CompoZr® Zinc Finger Nuclease (ZFN) technology in a proprietary renal proximal tubule epithelial cell line.

Glutamine Metabolism is Dysregulated in Many Cancer Cells

Sigma-Aldrich presents an article about how proliferatively active cells require both a source of carbon and of nitrogen for the synthesis of macromolecules. Although a large proportion of tumor cells utilize aerobic glycolysis and shunt metabolites away from mitochondrial oxidative phosphorylation, many tumor cells exhibit increased mitochondrial activity.
