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.

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2 mL bacteriostatic water to the lyophilized vial. Swirl gently until clear — this short tetrapeptide dissolves within 1 minute.
How should this peptide be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 4 weeks.
What purity is this QSC compound and how is it verified?
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.
