La L-glutamine est un acide aminé essentiel qui sert d′importante source d′énergie aux cellules en culture et constitue un composant crucial des milieux de culture. La L-glutamine est très stable sous forme de poudre sèche ou de solution congelée. Elle se dégrade toutefois assez rapidement dans les milieux liquides et les solutions mères. L′atteinte de performances cellulaires optimales nécessite généralement l′ajout d′un supplément en L-glutamine au milieu avant utilisation.

Analysis Note

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

Application

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.
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.

General description

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.

Other Notes

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