What is Cortagen??

Cortagen (Ala-Glu-Asp-Pro, AEDP, molecular formula C17H27N5O8, MW 430.17 g/mol) is a synthetic tetrapeptide bioregulator from the Khavinson Cytogen family, developed at the St. Petersburg Institute of Bioregulation and Gerontology. It primarily targets cerebral cortex tissue through tissue-specific DNA promoter binding and nuclear gene expression modulation. Research in neural models demonstrates that Cortagen hyperpolarises neurons, reduces spontaneous firing, and exhibits neuroprotective and nerve-regenerative properties. Microarray studies in mouse heart tissue also identified significant gene expression changes – indicating secondary cardiovascular activity. Cortagen is distinct from Epithalon (a related tetrapeptide) in its amino acid composition and resulting tissue targeting specificity.

Research Applications

CNS Neuroprotection

Neuronal hyperpolarisation, reduced spontaneous activity, ischaemic brain injury attenuation – neuronoprotective action profiling

Peripheral Nerve Regeneration

Injured nerve function restoration after transection, electrophysiological parameters, sciatic nerve recovery models

Brain Cortex Gene Expression

Microarray profiling of cortagen-induced gene changes in cortical tissue, DNA promoter binding specificity

Inflammatory Balance

CNS inflammatory pathway modulation, pro/anti-inflammatory cytokine equilibrium in neural tissue models

Anti-Ageing & Geroprotection

DNA repair toward youthful state, senescence reduction, age-related cortical decline reversal in geriatric models

Frequently Asked Questions

How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized vial by directing water down the inner wall of the vial. Swirl gently until the powder fully dissolves β€” do not shake or vortex. The solution should be clear and colourless. Use immediately or refrigerate at 2–8Β°C.
How should this peptide be stored?
Store lyophilized peptide vials at βˆ’20Β°C for long-term storage. Once reconstituted, store at 2–8Β°C (refrigerator) and use within 21–28 days. Avoid repeated freeze-thaw cycles, direct light, and heat exposure.
What purity is this QSC compound and how is it verified?
All QSC compounds are tested to β‰₯99% purity by HPLC peak area analysis on every production batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
