Solubility: Highly soluble in water, PBS, and physiological saline; insoluble in organic solvents.
Premium Quality & Manufacturing Excellence
Our Cortagen Premium is produced under strict GMP-compliant conditions in a Class 100 cleanroom, utilizing advanced solid-phase peptide synthesis (SPPS) technology. Every batch undergoes rigorous quality control:
Dual Purity Testing: In-house HPLC analysis followed by third-party mass spectrometry (MS) validation to confirm ≥99.0% purity.
Impurity Screening: Zero heavy metals, endotoxins (<0.01 EU/mg), and microbial contaminants, with full COA (Certificate of Analysis) and MSDS provided for every order.
Stability Assurance: Optimized lyophilization process preserves peptide integrity, ensuring consistent activity across storage and transportation.
Mechanism of Action & Research Applications
Cortagen Premium acts as a potent CNS bioregulator, crossing the blood-brain barrier efficiently to modulate gene expression in cerebral cortex neurons and glial cells. Its key mechanisms include:
Epigenetic Regulation: Modulates chromatin structure and activates neurotrophic factor genes (BDNF, NGF), supporting synaptic plasticity and neuronal survival.
Oxidative Stress Reduction: Inhibits lipid peroxidation and enhances endogenous antioxidant systems, protecting neurons from age-related damage.
Neuroregeneration: Stimulates nerve fiber growth (27–40% increase in preclinical models) and accelerates recovery from cerebral ischemia and neural injury.
Primary research applications include:
Cognitive Aging: Improves spatial memory, attention, and executive function in aged animal models.
Neuroprotection: Reduces neuronal apoptosis and preserves cortical thickness in neurodegenerative models.
Neural Repair: Enhances recovery from stroke, traumatic brain injury, and peripheral nerve damage.
Geroprotection: Reverses age-related gene silencing and promotes cellular rejuvenation in neural tissue.
