• Circadian rhythm regulation research: Studying the interaction between peptide substances and the body’s circadian clock system, analyzing their effects on hormone secretion rhythms and physiological cycle stability.

1.2 Neuroprotection and Stress Response Research

• Neural cell protection research: Exploring the protective effects of peptide substances on neurons under stress conditions, analyzing their regulatory mechanisms on oxidative stress and inflammatory responses in nerve cells.
• Stress response regulation research: Studying the regulatory effects of related peptides on the body’s stress response system, including the hypothalamic-pituitary-adrenal axis and sympathetic nervous system activity, to clarify their role in maintaining neuroendocrine balance.
• Cognitive function and brain health research: Investigating the potential effects of peptide substances on cognitive function, memory and learning ability in preclinical models, providing new ideas for the study of neurodegenerative diseases and cognitive decline mechanisms.

2. Advanced Production and Quality Control System

1. Solid-Phase Peptide Synthesis: The target peptide sequence is assembled using Fmoc or Boc protection chemistry on a solid resin support, which can accurately control the amino acid addition sequence and minimize side reactions. This method is suitable for producing polypeptides with complex sequences, ensuring that the molecular structure is completely consistent with the design.
2. Cleavage and Deprotection: The completed peptide is cleaved from the resin, and protecting groups are removed using professional reagents to ensure the purity and activity of the final product.
3. High-Precision Purification: Preparative reversed-phase high-performance liquid chromatography (RP-HPLC) is used to purify the crude product, separating the target peptide from impurities based on differences in molecular hydrophobicity, achieving a purity of ≥99%.
4. Vacuum Freeze-Drying: The purified peptide is freeze-dried into a stable white powder, which can effectively lock the molecular activity structure, avoid the damage of high-temperature drying to the peptide structure, and extend the storage period.

• HPLC Purity Analysis: Quantitative assessment of product purity to ensure compliance with research-grade standards.
• Mass Spectrometry Verification: Confirmation of the molecular weight and structural correctness of the peptide to ensure no sequence deviation or modification.
• Residual Solvent and Moisture Testing: Ensuring that residual solvents and moisture content meet safety limits to prevent degradation during storage.
• Endotoxin Testing: For cell culture and in vivo experiments, endotoxin levels are tested to ensure they meet the requirements of biological experiments.
