To order Chonluten for bronchial epithelial cell assays, principal investigators must evaluate supplier pricing structures based on verified analytical standards rather than surface-level milligram costs. Institutional pricing for laboratory-grade Chonluten typically scales with batch volume, purity thresholds, and the rigors of third-party quality control. Researchers sourcing compounds for delicate cell culture models require high-purity material to prevent batch-to-batch variability and off-target cytotoxic effects.
PX1 Research maintains a transparent catalog structure for short bioregulatory peptides, providing clear analytical documentation for every lot. Investigators can review our complete selection of research peptides or navigate directly to the dedicated Chonluten product page to obtain lot-specific data sheets, purity profiles, and institutional order options. For large-scale screening protocols, laboratories can establish streamlined procurement through our wholesale account portal.
Chonluten is a synthetic bioregulatory tripeptide consisting of the amino acid sequence L-Lysyl-L-Glutamyl-L-Aspartic Acid (Lys-Glu-Asp or KED). With a low molecular weight, this peptide belongs to a specific class of short chain peptide bioregulators designed to interact with chromatin structures and nuclear regulatory regions in mammalian cell lines. Its concise sequence allows for predictable chemical stability and reliable solubility in aqueous culture media.
In chemical synthesis, Chonluten is produced via solid-phase peptide synthesis (SPPS) under GMP-compliant conditions. The resulting peptide is purified to eliminate residual trifluoroacetic acid (TFA) salts, unreacted amino acid precursors, and organic solvents. Precision synthesis guarantees that the charged side chains of lysine, glutamic acid, and aspartic acid remain fully functional for binding assays in bronchial epithelial cell lines.
Preclinical studies indicate that Chonluten modulates gene expression in primary bronchial epithelial cells and established lung cell lines. The primary mechanism of action involves the sequence-specific interaction of the KED tripeptide with double-stranded DNA promoter regions. In vitro assays demonstrate that short bioregulatory peptides can penetrate cell membranes and nuclear envelopes to bind directly with histone proteins and specific DNA sequences, altering chromatin condensation state.
In airway epithelial models, this genomic interaction promotes the upregulation of functional proteins involved in cellular differentiation, structural integrity, and mucociliary clearance mechanisms. In vitro data indicate that exposure to Chonluten alters the transcription of heat shock proteins, antioxidant enzymes, and cell-junction complexes, thereby enhancing cellular resistance against oxidative stress and environmental toxins.
In vitro research using primary human bronchial epithelial cells (HBECs) highlights the capacity of Chonluten to regulate inflammatory signaling cascades. When cell cultures are exposed to inflammatory triggers such as lipopolysaccharide (LPS) or tumor necrosis factor-alpha (TNF-α), pretreatment with Chonluten attenuates the overproduction of pro-inflammatory cytokines, including interleukin-6 (IL-6) and interleukin-8 (IL-8).
Rodent models of acute lung injury and chronic airway inflammation further illustrate the compound's pulmonary activity. Preclinical animal studies suggest that administration of KED tripeptide preserves alveolar architecture, reduces neutrophil infiltration into bronchoalveolar lavage fluid, and accelerates repair of damaged mucosal tissue. Investigators studying tissue engineering and organoid models frequently use Chonluten to assess epithelial barrier maintenance and transepithelial electrical resistance (TEER).
When designing tissue-specific cell culture assays, researchers often compare Chonluten against other bioregulatory short peptides to determine sequence-dependent specificity. While Chonluten specifically targets bronchial and pulmonary epithelial transcription, related peptides exhibit distinct cellular tropisms and metabolic influences.
For instance, Bronchogen (Ala-Glu-Asp-Pro) is another tetrapeptide heavily investigated in pulmonary tissue models for respiratory function support, whereas Vilon (Lys-Glu) serves as a broader immunomodulatory dipeptide targeting thymic and lymphocyte proliferation. Similarly, Epithalon (Ala-Glu-Asp-Gly) is selected for general cellular senescence and telomerase activity studies rather than specialized bronchial epithelial markers. Laboratories evaluating cellular repair cascades may also cross-reference general tissue repair compounds like BPC-157 in multi-compound comparative arrays.
The pricing of research-grade Chonluten is determined by several rigorous manufacturing and quality assurance parameters. Low-cost peptides frequently omit critical analytical testing, leaving laboratories vulnerable to batch contamination, inaccurate molar concentrations, or presence of cytotoxic lipopolysaccharides. High-purity compounds require sophisticated purification steps that increase unit yield costs but protect experimental reproducibility.
Key cost drivers for high-integrity research reagents include:
1. HPLC Purity Thresholds: Achieving ≥98% chromatographic purity requires extensive reverse-phase liquid chromatography (RP-HPLC) fraction collection.
2. Endotoxin Removal: In vitro cell cultures are exceptionally sensitive to bacterial endotoxins; removing LPS to <0.01 EU/mg requires specialized chromatography resins.
3. Mass Spectrometry Validation: Sequence verification via Electrospray Ionization Mass Spectrometry (ESI-MS) confirms exact molecular weight without side-chain modifications.
4. Third-Party COA Testing: Independent testing in an ISO 17025 accredited laboratory adds verifiable analytical trust to every batch.
PX1 Research enforces strict quality control parameters for every lot of Chonluten. Every vial is produced in USA-based, GMP-compliant manufacturing facilities and undergoes full batch analysis before release. Principal investigators can download a lot-specific Certificate of Analysis (COA) directly from our research portal.
Our analytical testing protocol includes RP-HPLC to confirm physical purity, ESI-MS to confirm peptide identity and exact mass, and chromogenic LAL assays to verify low endotoxin levels. By eliminating contaminants and counter-ion toxicity, PX1 Research ensures that observed experimental outcomes in bronchial epithelial assays are directly attributable to the pure KED peptide sequence.
Proper reconstitution of lyophilized Chonluten is necessary to preserve peptide stability and ensure accurate dosing in cell culture media. Lyophilized Chonluten appears as a white, sterile powder and should be reconstituted using sterile, endotoxin-free water or phosphate-buffered saline (PBS, pH 7.4).
To prepare stock solutions for in vitro experiments, allow the vial to equilibrate to room temperature before adding the reconstituting solvent. Gently swirl or invert the vial until complete dissolution is observed; vigorous vortexing or sonication should be avoided to prevent mechanical shearing of the peptide chain. Once dissolved, stock solutions can be sterile-filtered through a 0.22 µm low protein-binding filter before addition to bronchial epithelial growth media.
Lyophilized Chonluten powder maintains optimal chemical stability when stored at -20°C in a desiccated, dark environment. Under these conditions, the lyophilate remains stable for up to 24 months from the date of manufacture. Exposure to ambient moisture, elevated temperatures, or direct ultraviolet light can induce peptide degradation or oxidation.
Reconstituted liquid stock solutions should be divided into single-use aliquots to prevent repeated freeze-thaw cycles, which degrade peptide integrity. Aqueous aliquots stored at -20°C or -80°C remain stable for up to 3 to 6 months. Short-term storage of reconstituted solution at 2°C to 8°C should not exceed 7 to 14 days.
