一般說明

L-谷氨酰胺被发现是血流中最丰富的氨基酸之一。 它可用于许多生物化学过程,如生产其他氨基酸、葡萄糖、核苷酸、蛋白质和谷胱甘肽。 它还可以用作增加肠绒毛高度、维持粘膜完整性和刺激肠粘膜细胞增殖的补充剂。 由于它具有抑制肠道和口腔毒性副作用的功能,它还可以应用于化学疗法和放射疗法的治疗中。
该有证标准物质(CRM)是根据ISO/IEC 17025ISO 17034生产和认证的。该CRM可追溯到来自NMI的原材料,如 NIST或NMIJ。
证书上给出了定量核磁共振法认证的内容,包括不确定性和失效日期。

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。

包裝

Failure of cytotoxic T lymphocytes (CTLs) or natural killer (NK) cells to kill target cells by perforin (Prf)/granzyme (Gzm)-induced apoptosis causes severe immune dysregulation. In familial hemophagocytic lymphohistiocytosis, Prf-deficient infants suffer a fatal "cytokine storm" resulting from macrophage overactivation, but

Helminth parasites remain one of the most common causes of infections worldwide, yet little is still known about the immune signaling pathways that control their expulsion. C57BL/6 mice are chronically susceptible to infection with the gastrointestinal helminth parasite Heligmosomoides polygyrus.

Autophagy is a catabolic process that allows cells to digest their cytoplasmic constituents via autophagosome formation and lysosomal degradation. Recently, an autophagy-specific phosphatidylinositol 3-kinase (PI3-kinase) complex, consisting of hVps34, hVps15, Beclin-1, and Atg14L, has been identified in mammalian cells. Atg14L

Medullary thymic epithelial cells (mTECs) expressing the autoimmune regulator AIRE and various tissue-specific antigens (TSAs) are critical for preventing the onset of autoimmunity and may attenuate tumor immunity. However, molecular mechanisms controlling mTEC development remain elusive. Here, we describe the
