Bronchogen 20mg (10 Vials / Kit)

Bronchogen at a glance

Bronchogen is a four-residue synthetic peptide, Ala-Glu-Asp-Leu, often shortened to AEDL. It was developed within the Khavinson bioregulator program, which designed short sequences intended to reproduce activity attributed to tissue extracts, in this case from the bronchial mucosa. The formula is C18H30N4O9 and the molecular weight 446.45 g/mol. It is supplied as a freeze-dried powder and is one of the more chemically well-defined members of that peptide family.

Price and availability

SSRBIO lists this kit of 10 vials at 20mg each (200 mg in total), shipped from China. At $87.60 for the kit, that works out to $0.438 per mg. Of the 3 Bronchogen listings on the marketplace, from 3 brands, this is the lowest price per mg. Your payment waits in escrow until you confirm the parcel arrived, and only then is it released to the brand.

What it is studied for

Bronchogen is proposed to act on transcription inside airway cells instead of at a membrane receptor. Reports from bronchial epithelial cultures describe altered expression of differentiation factors including NKX2-1 and FOXA1/FOXA2, and of secretoglobin genes associated with club cells. In rodent lung injury models, investigators have reported changes in inflammatory cell counts and mucus-related markers. Some modeling studies suggest the tetrapeptide can bind specific DNA motifs or histone sites, but those interactions have not been confirmed by independent structural work.

Research and regulatory status

Research remains preclinical: cell culture, bleomycin-induced fibrosis and other rodent airway injury experiments, published mainly by the originating group and its collaborators. No randomized human trial has been reported, and Bronchogen is not an approved respiratory medicine. Results are useful for generating hypotheses about short-peptide gene regulation in lung tissue, but they do not establish effects in people. GLP1 Forum Escrow lists it strictly for laboratory research.

Checking the lab data

With a defined formula, identity is straightforward: mass spectrometry should show a molecular ion consistent with 446.45 g/mol, ideally with fragmentation confirming the Ala-Glu-Asp-Leu order rather than a scrambled isomer. HPLC purity needs its chromatogram and a method appropriate for an acidic, polar tetrapeptide. Look for peptide content, counter-ion, a white lyophilized appearance and a batch number that matches the vial.

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 20 mg vial dissolved in 2 mL gives 10 mg/mL, or 20 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
