Description

Selenocysteine is the 21st proteinogenic amino acid, a key component of selenoproteins essential for antioxidant defense and redox regulation. This unique selenium-containing compound is critical for research and development in biochemistry and pharmaceuticals, where its role in enzymatic activity is studied. It serves as a vital building block for scientists and manufacturers in the nutraceutical, research chemical, and advanced life science sectors seeking high-purity biochemical precursors.

Application

• Biochemical Research: Essential precursor for the study and synthesis of selenoproteins, such as glutathione peroxidases and thioredoxin reductases.
• Pharmaceutical Development: Investigated for use in novel therapeutic agents targeting oxidative stress-related diseases and cancer.
• Nutraceutical Formulation: Incorporated into advanced dietary supplements designed to support cellular antioxidant systems.
• Enzymology Studies: Used to incorporate selenium into active sites of enzymes for mechanistic and structural studies.
• Cell Culture Media: A specialized component in defined media for culturing certain cell lines requiring selenium in organic form.
• Reference Standard: Serves as a high-purity analytical standard in HPLC, LC-MS, and other quality control methods for related compounds.

Quality Control

Our Selenocysteine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification and heavy metal screening, to ensure it meets the stringent requirements for research and development applications. A Certificate of Analysis (COA) detailing purity, identity, and specific tests is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. Due to its hygroscopic and light-sensitive nature, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent oxidation and moisture absorption. Keep away from strong oxidizing agents.
