Descrição

Amino Acid Sequence

γ-Glu-Cys-Gly

Descrição geral

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.

Aplicação

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.

Pode ser usado na concentração de 5-10 mM para eluir glutationa S-transferase (GST) de agarose com glutationa.

Ações bioquímicas/fisiológicas

Antioxidante endógeno que tem um papel importante na redução das espécies reativas de oxigênio formadas durante o metabolismo celular e a “explosão respiratória”. A glutationa S-transferase catalisa a formação de tioéteres de glutationa com xenobióticos, leucotrienos e outras moléculas que têm um centro eletrofílico. A glutationa também forma pontes bissulfeto com resíduos de cisteína em proteínas. Por meio desses mecanismos, ela pode ter o efeito paradoxal de reduzir a eficácia de agentes antineoplásicos.

Nota de análise

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