Description

Amino Acid Sequence

γ-Glu-Cys-Gly

General description

Glutathione (GSH) is the most important nonprotein thiol widely distributed in animal tissues, plants, and microorganisms. GSH is also a key determinant of redox signaling and protection against oxidative stress.
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.

Application

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.

Puede utilizarse a 5-10 mM para eluir la glutatión S-transferasa (GST) a partir de glutatión agarosa.

Biochem/physiol Actions

Antioxidante endógeno que desempeña un papel importante en la reducción de las especies de oxígeno reactivo formadas durante el metabolismo celular y el estallido respiratorio. La glutatión-S-transferasa cataliza la formación de tioéteres de glutatión con xenobióticos, leucotrienos y otras moléculas que tienen un centro electrofílico. El glutatión también forma enlaces de disulfuro con restos de cisteína de las proteínas. A través de estos mecanismos, puede tener el efecto paradójico de reducir la eficacia de los antineoplásicos.

Analysis Note

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

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.
