一般描述

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. L -glutamine is the most abundant amino acid in the body. It is essential for the synthesis of L -asparagine. It also helps in muscle growth through protein synthesis and increased growth hormone levels.

应用

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
L -Glutamine may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using amperometric L -glutamate oxidase based enzyme sensors.

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。

分析说明

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.

其他说明

This Certified Reference Material (CRM) is produced and certified in accordance withISO 17034andISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
