What is Bronchogen?

Bronchogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Leu) developed through the Khavinson peptide bioregulator programme. Acts as a tissue-specific geroprotector for bronchial and lung epithelium, studied for modulation of airway cell proliferation, differentiation, and gene expression normalisation in aged tissue. Research use only.

Research Applications

Bronchial Epithelium Research

Airway cell differentiation, ciliary function, mucociliary clearance

Frequently Asked Questions

How do I reconstitute Bronchogen?
Add 1–2 mL bacteriostatic water to the lyophilized vial. Swirl gently until clear — this short tetrapeptide dissolves within 1 minute.
How should Bronchogen be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 4 weeks.
What is a peptide bioregulator?
Peptide bioregulators are short (2–4 amino acid) tissue-specific peptides developed by the St. Petersburg Institute of Bioregulation and Gerontology. They are proposed to normalise gene expression in target tissues and act as geroprotectors. Bronchogen targets bronchial/lung epithelium.
