应用

L-谷氨酰胺已作为培养基补充剂用于：
  • 耳蜗器官型培养
  • Iscove′s改良Dulbecco′s培养基中，以进行HeLa细胞培养
  • Dulbecco′s改良Eagle′s培养基中，以进行肝细胞原代培养

生化/生理作用

L-谷氨酰胺是一种必需氨基酸，是培养基的重要成分，也是培养细胞的主要能源。最佳的细胞性能通常需要在使用前添加 L-谷氨酰胺的培养基。
谷氨酰胺通过细胞mTOR（雷帕霉素的哺乳动物靶标）信号转导介导蛋白质的周转。其还已报到可与细胞凋亡的抑制有关。
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。

包装

带橡胶塞的 50 mL 琥珀色血清瓶。

适用性

适用于细胞培养应用，尤其是无血清细胞培养。

重悬

用无菌水复溶至 10 mL 时，制备 200 mM 溶液。

其他说明

二肽 L-Ala-LGln 经常用于现代无血清培养基配方中，因为它在体外提供了更稳定的谷氨酰胺形式。

Cell-matrix adhesions are central mediators of mechanotransduction, yet the interplay between force and adhesion regulation remains unclear. Here we use live cell imaging to map time-dependent cross-correlations between vinculin-mediated tension and adhesion complex area, revealing a plastic, context-dependent relationship. Interestingly
