L-谷氨酰胺 (200 mM)

L-谷氨酰胺是细胞培养所必需的一种氨基酸。L-谷氨酰胺参与嘌呤和嘧啶核苷酸、氨基糖类、谷胱甘肽、L-谷氨酸和其他氨基酸的形成,并参与蛋白质的合成和葡萄糖的产生。与大多数其他氨基酸不同,L-谷氨酰胺在溶液中不稳定。降解速率是时间、温度和 pH 的函数了解更多信息

我们还提供 Gibco™ GlutaMAX™ 补充剂作为 L-谷氨酰胺的稳定替代产品。

双生产现场 cGMP 生产和质量体系
Gibco™ L-谷氨酰胺是在位于英国苏格兰佩斯利的一家符合 cGMP 要求的工厂内生产的。该工厂是在 FDA 注册的医疗器械生产商,且通过 ISO 13485 标准认证。为确保供应链连续性,我们同时提供由我们格兰德岛工厂生产的等同 Gibco™ L-谷氨酰胺产品 (25030-081)。本工厂者亦是在 FDA 登记的医疗器械生产商,且符合 ISO 13485 标准。

常见问题解答 (FAQ)

为何我的200 mM L-谷氨酰胺在化冻后出现沉淀?

浓储存液中的L-谷氨酰胺在低温下易于发生沉淀。在37°C水浴中短暂加热储存液并辅以温和的摇动,就可溶解沉淀。在沉淀完全溶解之前不要使用本品。

Why did my 200 mM L-Glutamine precipitate out of solution when I thawed it?

When L-glutamine is in a concentrated stock solution it easily precipitates when cooled. Warming the solution briefly in a 37C water bath with gentle swirling will dissolve the precipitate. Do not use the product unless the precipitate is fully dissolved.

Why does L-Glutamine (200 mM) (Cat. No. 25050149, 25030081, 25030164) solution have “Product of Brazil” on the label?

L-Glutamine (200 mM) (Cat. No. 25050149, 25030081, 25030164) solution is made in the USA from a raw material glutamine powder manufactured in Brazil. The country of manufacture of a component that has been subjected to manufacturing or processing operations in more than one country is the last country in which the component has been “substantially transformed”. A “substantial transformation” occurs in a country when a product emerges from a manufacturing process with a name, character, or use different from that of the original material(s) subjected to that process.

Diluting, purifying, sorting, testing, packing, repacking, or affixing labels to a product in a country does not constitute a “substantial transformation” in that country, hence the label must bear the country of the original raw material origin.

My order of L-Glutamine (Cat. No. 25030081) arrived frozen. Is it stable?

If L-Glutamine is completely or partially frozen, it is still stable. It becomes unstable when stored for extended periods of time completely thawed, especially above 2-8 degrees C.

What is your recommended method for thawing L-Glutamine before adding to cell culture media?

We recommend thawing at 2-8 degrees C and then warming at 37 degrees C until the material goes into solution. Mix it as it warms up to spend minimal time at elevated temperatures before you aliquot it.
