Product Detail

Basic Parameter Information

Full Name: Bronchogen Lung Tissue Regulatory Tripeptide

Amino Acid Sequence: H-Glu-Asp-Arg-OH

Molecular Formula: C₁₄H₂₆N₆O₈

Molecular Weight: 406.39 g/mol

CAS Number: Custom synthetic tissue bioregulator without universal public CAS registration number

Appearance: Sterile lyophilized white crystalline powder, individually sealed in separate vials (main specifications: 10mg / 20mg / 50mg)

Purity: ≥99% verified by HPLC detection, complete COA quality inspection documents are provided with every production batch

R&D Background: Bronchogen is a targeted short tripeptide bioregulator from the peptide gerontology research system, derived from the active functional fragments of pulmonary mucosal tissue endogenous polypeptides. This high-purity synthetic laboratory raw material is developed for bronchial epithelial cell cultivation, pulmonary barrier function testing, chronic respiratory inflammatory cell model research and age-related lung tissue degenerative mechanism exploration. It is widely used in respiratory cell biology, airway mucosal regeneration and pulmonary aging pathology laboratory projects.

2. Core Mechanism of Action

Bronchogen easily penetrates respiratory epithelial cell membranes and acts on gene regulatory segments related to lung tissue homeostasis, activating multi-layer mucosal protection and tissue repair signaling networks in in vitro culture systems:

Stimulate the proliferation and renewal capacity of primary bronchial epithelial precursor cells, maintain stable viable cell quantity during long-term cell incubation and slow the decline of mucosal cell vitality;

Upregulate the expression of mucous barrier structural proteins and tight junction related factors, consolidate the integrity of airway epithelial monolayer and reduce abnormal substance leakage under irritant stimulation;

Suppress the over-secretion of pro-inflammatory signaling factors in airway resident immune cells, rebuild a mild tissue microenvironment and alleviate continuous inflammatory erosion of bronchial mucosal structures;

Restrain the overexpression of tissue matrix degradation enzymes triggered by chronic stimulation, reduce excessive breakdown of extracellular support structures and prevent irreversible remodeling of airway tissue;

Enhance the expression of intracellular antioxidant proteins in lung epithelial cells, clear accumulated oxidative metabolites and relieve cellular senescence caused by long-term stress stimulation;

Optimize signal communication between bronchial epithelial cells and pulmonary stromal cells, balance metabolic activity of mixed lung tissue co-culture systems under simulated adverse environmental conditions.

3. Core Research Efficacy (For Research Laboratory Use Only)

Bronchial Epithelial Cell Culture & Airway Barrier Research

Core experimental probe for cultivating primary respiratory mucosal cells, suitable for quantitative detection of tight junction protein expression and mucosal barrier integrity test assays.

Chronic Respiratory Inflammation Cell Model Research

Key raw material for exploring persistent airway inflammatory injury pathways, supporting cell-level experiments simulating irritant-induced bronchial tissue damage.

Lung Tissue Anti-Senescence & Oxidative Protection Research

Auxiliary testing reagent for senescent pulmonary cell culture systems, applied to mechanistic analysis of oxidative damage relief and epithelial cell function restoration.

Airway Tissue Remodeling Regulatory Mechanism Research

Balance catabolic and anabolic signals of extracellular matrix, ideal for laboratory research on restraining abnormal airway structural fibrosis and reconstruction.

Mixed Pulmonary Tissue Co-Culture Microenvironment Research

Coordinate interactive regulatory signals between epithelial and stromal cells, supporting exploration of homeostasis maintenance mechanisms in lung local tissue microenvironment.

Supplied as sterile lyophilized white crystalline powder with HPLC-certified purity ≥99%, mainstream vial specifications include 10mg, 20mg and 50mg. Every batch is attached with full supporting documents covering COA, MSDS and HPLC chromatogram test records.

As a lung-specific short tripeptide laboratory reagent, Bronchogen integrates bronchial epithelial renewal promotion, airway barrier reinforcement, inflammatory balance regulation and anti-senescence protective effects. Its small molecular chain delivers excellent water solubility and stable cell permeability, maintaining consistent tissue-targeted regulatory activity across various in vitro respiratory epithelial and mixed lung tissue co-culture research systems.

It serves as indispensable research material for cell cultivation and tissue model experiments covering respiratory mucosal regenerative biology, airway inflammatory balance, pulmonary cell senescence and chronic airway tissue remodeling research.

Note: For laboratory research experimental use only, not approved for human oral intake or clinical therapeutic preparation application.
